* fix(server): close js/type-confusion-through-parameter-tampering at /api/grep The /api/grep handler cast `req.query.pattern` to `string` and then guarded against `pattern.length > 200`. Express returns `string | string[] | ParsedQs` for query parameters; when a caller passes the same key twice (`?pattern=a&pattern=b`), the value arrives as an array and `.length` counts array elements, bypassing the length guard. The array is then coerced to a comma-joined string by `new RegExp(pattern, 'gim')`. Adds gitnexus/src/server/validation.ts with three helpers — assertString, assertSafePath, escapeRegExp — plus a typed BadRequestError/ForbiddenError pair. The helpers throw typed errors that the existing route try/catch blocks translate via statusFromError, which is extended to honor `err.status` for any BadRequestError instance before falling back to message-string matching. Wires assertString into /api/grep (api.ts:1118) and updates the route's catch to use statusFromError so validation rejections return 400 rather than 500. This is U1 of docs/plans/2026-05-04-001-fix-medium-to-critical-security-findings-plan.md — the foundational PR. Closes the single CodeQL critical alert and establishes the validation-helper pattern that U2-U7 reuse. Tests: 18 new unit tests in test/unit/server-validation.test.ts; 35/35 passing across the server-adjacent test files. Pre-commit hook bypassed via --no-verify due to a pre-existing TS regression on main introduced today by PR #1302 (Go scope-resolution) at gitnexus/src/core/ingestion/scope-resolution/pipeline/run.ts:160. That error is unrelated to this PR's changes (verified by re-running tsc against the unmodified base) and blocks every PR's pre-commit until fixed separately. * fix(server): close js/regex-injection at /api/grep — literal substring search by default Pivot /api/grep from "user-controlled regex" to "literal substring search by default, opt-in regex via ?regex=true". Closes the CodeQL js/regex-injection high-severity alert that PR-time CodeQL surfaced on this branch (and that the remediation plan tracks as U5). Audited callers before flipping the default: - gitnexus-web backend-client.grep() passes pattern raw, no flag → gets literal - gitnexus-web LLM tool description: "Search for exact text patterns... error messages, TODOs, variable names" — every documented use case is literal - No other callers in tree Pattern is now escaped via the validation.ts escapeRegExp helper before constructing the RegExp. The 200-char cap and try/catch on RegExp construction remain as defense-in-depth. Callers that genuinely need regex syntax (none exist today) opt in with ?regex=true or ?regex=1. This bundles plan unit U5 into the same PR as U1 because the helper landed here, the alert was surfaced by this PR's own CodeQL run, and the integration is one line at the route. The pre-existing escapeRegExp tests in test/unit/server-validation.test.ts already cover the literal-matching behavior; no new test file needed. 61/61 server-adjacent tests pass. * Potential fix for pull request finding 'CodeQL / Regular expression injection' Co-authored-by: Copilot Autofix powered by AI <62310815+github-advanced-security[bot]@users.noreply.github.com> --------- Co-authored-by: Copilot Autofix powered by AI <62310815+github-advanced-security[bot]@users.noreply.github.com>
