fix(sse): add first-byte watchdog to the TLS-fingerprint transport (#12656 )

The wreq-js TLS-fingerprint transport resolved the Response as soon as upstream headers arrived, with zero guard around how long the caller then waited for the body's first byte. TlsClient's only timing control, a flat timeout, defaults to 600_000ms, matching the reported 90-600s stall window exactly. Add guardTlsFirstByte() (open-sse/utils/tlsFirstByteWatchdog.ts), which races the body's first read() against a short, env-overridable watchdog (TLS_FIRST_BYTE_WATCHDOG_MS, default 10s). A healthy body is unaffected (bytes already buffered are replayed through a passthrough stream); a stalled body cancels the wreq reader and throws, letting proxyFetch's existing TLS-fallback catch blocks fall through to the direct/proxy dispatcher. A non-replay-safe request (e.g. a POST with a body) still throws instead of being silently retried, reusing isTlsFallbackReplaySafe.
chore(deps): drain the Dependabot queue — 10 of 13 alerts (#13213 )

diegosouzapw	3ce03abae3	fix(sse): add first-byte watchdog to the TLS-fingerprint transport (#12656 ) The wreq-js TLS-fingerprint transport resolved the Response as soon as upstream headers arrived, with zero guard around how long the caller then waited for the body's first byte. TlsClient's only timing control, a flat timeout, defaults to 600_000ms, matching the reported 90-600s stall window exactly. Add guardTlsFirstByte() (open-sse/utils/tlsFirstByteWatchdog.ts), which races the body's first read() against a short, env-overridable watchdog (TLS_FIRST_BYTE_WATCHDOG_MS, default 10s). A healthy body is unaffected (bytes already buffered are replayed through a passthrough stream); a stalled body cancels the wreq reader and throws, letting proxyFetch's existing TLS-fallback catch blocks fall through to the direct/proxy dispatcher. A non-replay-safe request (e.g. a POST with a body) still throws instead of being silently retried, reusing isTlsFallbackReplaySafe.	2026-09-10 15:35:13 -03:00
Diego Rodrigues de Sa e Souza	fd27ff08c7	chore(deps): drain the Dependabot queue — 10 of 13 alerts (#13213 ) * chore(deps): drain the Dependabot queue — 7 of 10 alerts Lockfile-only bumps; no manifest touched, so nothing changes for consumers. Root package-lock.json: hono 4.13.0 -> 4.13.7 (#215 #216 #217, medium, patched 4.13.5) csv-parse 7.0.1 -> 7.0.2 (#213, medium) joi 18.2.3 -> 18.2.8 (#211 #212, low, patched 18.2.4/18.2.5) @omniroute/opencode-plugin: toml 4.1.1 -> 4.3.0 (#209, HIGH, patched 4.1.2) @omniroute/opencode-plugin-v2: esbuild 0.28.1 -> 0.28.2 (#210, low) — the direct copy only; see below. The plugin-v2 diff looks large but is one package: esbuild ships 27 platform binaries, each carrying version + resolved + integrity. Three alerts stay open, deliberately: #218 extract-zip (HIGH) and #214 adm-zip (medium) have NO published patch. Both are dev-scope. Closing them needs an upstream release or a decision to replace the dependency — neither belongs in a lockfile bump. #210 esbuild is only half-closed. `node_modules/esbuild` is on 0.28.2, but `tsup` pins `esbuild: ^0.27.0`, so its nested copy stays at 0.27.7 — inside the vulnerable range (>= 0.27.3, < 0.28.1). Updating tsup does not move it (8.5.1 is already current). Forcing it would take an `overrides` entry pushing a major of esbuild inside the bundler, which is exactly the change that breaks a build silently, for a LOW dev-only alert. Left for an upstream tsup release. check:lockfile passes on all three, including the workspace lock/manifest consistency check. check:tracked-artifacts OK. * chore(deps): bump js-yaml to 4.3.2 (root + electron) Two more HIGH alerts arrived after the first sweep: #220 js-yaml (root package-lock.json) >= 4.0.0, < 4.3.2 #219 js-yaml (electron/package-lock.json) >= 4.0.0, < 4.3.2 The root's own js-yaml was already on 5.4.1; the vulnerable copies were the ones nested under @yarnpkg/parsers, lockfile-lint, xmlbuilder2 (root) and the direct dependency in electron. All now 4.3.2. Four version lines, nothing else. #221 smol-toml (HIGH, <= 1.7.0) is NOT closed here. The root is on 1.8.0; the vulnerable 1.6.1 sits under @openai/codex-security, which pins it as an EXACT version rather than a range, so `npm update` cannot move it. Bumping codex-security itself (0.1.24 -> 0.1.26) does not help — 0.1.26 pins the same 1.6.1 — so that bump was reverted rather than carried along for no benefit. Closing #221 needs an upstream codex-security release or an `overrides` entry, the same trade already declined for #210/tsup: forcing a transitive pin from outside is how a build breaks silently. Note that @openai/codex-security is also the package carrying the unpatched extract-zip (#218), so one upstream release would likely clear both. * chore(deps): override smol-toml to 1.8.0 and raise the js-yaml floor Closes #221 (smol-toml, HIGH, DoS via malformed TOML, vulnerable <= 1.7.0). @openai/codex-security pins smol-toml at 1.6.1 as an EXACT version, so no `npm update` reaches it. This repo already uses `overrides` as its standard tool for exactly that situation — the block carries 20+ entries, including the scoped-by-parent form and the `qs`/`fast-uri`/`ip-address` entries that back earlier security bumps — so a scoped override is the idiomatic fix here, not a new mechanism: "@openai/codex-security": { "smol-toml": "^1.8.0" } The nested copy deduplicates to the root's existing 1.8.0, which two other consumers (the root itself and knip) already run, so the version is proven in this tree. The whole lockfile diff is the 14 lines of the removed 1.6.1 entry. Also raised the `@yarnpkg/parsers` js-yaml floor from ^4.3.1 to ^4.3.2, so the override documents the patched version rather than permitting the vulnerable one it was written against. Not fixed, and not fixable by version — verified against the npm registry rather than trusting the advisory metadata: #218 extract-zip — latest published IS 2.0.1, the vulnerable version. Dev scope, via @openai/codex-security. No release to move to. #214 adm-zip — latest published IS 0.6.0, the top of the vulnerable range (>= 0.5.9, <= 0.6.0). RUNTIME scope, via onnxruntime-node's ^0.5.16, and the repo already overrides adm-zip to ^0.6.0. No release to move to. Both need an upstream fix or a decision to replace the dependency; neither is a lockfile change. adm-zip being runtime rather than dev makes it the one worth tracking. #210 esbuild stays open too. A flat `overrides: { esbuild: ^0.28.2 }` in opencode-plugin-v2 does close it — npm then reports 0 vulnerabilities — but it requires regenerating that lockfile from scratch: 823 lines, 96 packages moved, for a LOW dev-only alert, and a major esbuild bump inside tsup cannot be validated here without a real install of that package. Tried, measured, reverted. Left for an upstream tsup release. check:lockfile OK on all lockfiles including the workspace consistency check; check:tracked-artifacts OK; prettier clean.	2026-09-10 13:37:55 -03:00
Diego Rodrigues de Sa e Souza	0549dcfc36	fix(api): scope batch bulk-delete to the calling API key (#13211 ) GHSA-wvxc-jp3v-5mg5: `DELETE /api/v1/batches/delete-completed` deleted the completed batches of EVERY api key on the instance and nulled the contents of every file those batches referenced. Any ordinary inference key reached it — including one with `scopes: []` — and no victim key, batch id or file id was needed. Two defects stacked in one endpoint: - `deleteCompletedBatches()` carried no `api_key_id` predicate. The file SELECT, the checkpoint DELETE and the batch DELETE were all instance-wide. - The route only checked that SOME key was present (`!scope.apiKeyId` → 401), never that the caller owned anything, and called the helper bare. The helper now takes `apiKeyId` and scopes all three statements to it; the route passes the caller's key and omits it only for session auth, so the operator's own dashboard keeps its instance-wide cleanup and an API key clears only its own completed batches. None of this is a new pattern. `listBatches(apiKeyId?)` and `countBatches(apiKeyId?)` in the same module already scope by `api_key_id`, and `batches/[id]/route.ts` already gates per-record access with `scopeCheck` — session auth sees everything, a key sees only its own. This one helper was the one that never got it, which is why the fix reuses the shape instead of inventing a second convention. tests/unit/batch-delete-completed-ownership-wvxc.test.ts — 5 tests, 4 red before the fix, including the two that prove the cross-tenant destruction (another key's batch survives; another key's file content survives). It also pins the instance-wide dashboard sweep so the fix cannot be "tightened" into breaking the operator's own cleanup, and a source guard that the route never calls the helper bare again. Reported privately via GHSA-wvxc-jp3v-5mg5. Closes GHSA-wvxc-jp3v-5mg5	2026-09-10 13:27:10 -03:00
Diego Rodrigues de Sa e Souza	393cfdd660	fix(test): make the ToS heading guard actually require the parentheses (#13228 ) CodeQL js/useless-regexp-character-escape (#994-#997) on one line, and it is a real defect rather than the usual query noise. The assertion built its pattern in a TEMPLATE literal: new RegExp(`\(\s${String(tos?.actual)}\s\)`) JavaScript resolves the escapes before RegExp ever sees the string: `\(` becomes "(" and `\s` becomes the LETTER "s". The compiled pattern was `(s16s)` — a capture group around optional "s" characters — so it matched any heading merely CONTAINING the number. The literal parentheses this guard exists to require were never checked, and it passed on exactly the headings it was written to reject: /(s16s)/.test("### Caution — clauses worth checking 16") // true Doubled the backslashes so they survive the template literal, and routed the interpolated value through an `escapeRegExp` helper — the count is a number today, but interpolating an unescaped value into a regex source is the same class of bug one refactor away. Added a second test that pins the behaviour rather than the spelling: the pattern must REJECT a heading carrying the count without parentheses, and accept it with them (including inner whitespace). Before this fix that test fails. 4/4 green against the real docs/reference/FREE_TIERS.md heading.	2026-09-10 13:27:02 -03:00
Diego Rodrigues de Sa e Souza	d86cf75aef	fix(quality): register 4 drifted covering tests in stryker tap.testFiles (#13229 ) `check:mutation-test-coverage --strict` has been failing Fast Quality Gates on every open PR against release/v3.8.51. It grew from 2 missing entries to 5 in roughly an hour, so it is drifting faster than PRs land. Four test files cover a mutated module without being listed, so their mutant kills do not count: open-sse/services/accountFallback.ts <- openai-compatible-per-upstream-402-health src/sse/services/auth.ts <- openai-compatible-per-upstream-402-health <- quota-window-label src/shared/utils/circuitBreaker.ts <- combo/execute-target-gates open-sse/services/combo/comboStructure.ts <- combo-pin-implicit-allowlist Registration only — no test or module is touched, and no gate is weakened; the listing is what makes those kills count in the first place. Inserted in place, never through a JSON round-trip: re-serializing this file reorders the ~10 curated entries that are already out of alphabetical order (learned the hard way in #11438). check:mutation-test-coverage now reports no drift. check:tracked-artifacts OK, prettier clean. Worth noting for whoever adds the next test: this gate fires whenever a NEW test happens to cover one of the 31 mutated modules, which is easy to do without realising. Registering it in the same commit is cheaper than a CI round-trip.	2026-09-10 13:26:53 -03:00
