fix(security): remediate undici vulnerabilities#2322
Merged
Conversation
Bump pnpm override to undici@>=6.27.0 to address four advisories: - GHSA-vxpw-j846-p89q (HIGH, CVSS 7.5): WebSocket DoS via fragment count bypass — unbounded memory growth from many small/empty continuation frames that each pass per-frame validation. - GHSA-p88m-4jfj-68fv (MEDIUM, CVSS 5.9): HTTP header injection via Set-Cookie percent-decoding. - GHSA-35p6-xmwp-9g52 (LOW): HTTP response queue poisoning via keep-alive socket reuse. - GHSA-g8m3-5g58-fq7m (LOW): Set-Cookie SameSite attribute downgrade via permissive substring matching. Fix lands undici@6.27.0 (or 7.28.0 / 8.5.0). The override bumps transitive consumers (@octokit/request, @actions/http-client) to undici 8.5.0 to satisfy the new floor. dist/ regenerated to reflect the bundled undici update. No source code changes — pure dependency remediation.

Summary
Remediates four Dependabot alerts for the transitive
undicidependency (consumed via@octokit/request,@actions/http-client, etc.) by bumping the pnpm override floor from>=6.23.0to>=6.27.0. This pulls in undici 8.5.0 transitively and closes all four advisories without modifying any source code.Advisories Addressed

Pure dependency remediation — no source code changes, no unrelated dependency bumps.
pnpm auditnow reports zero undici findings (advisories 54, 55, 56, 57 will auto-resolve on merge).Verification
pnpm run type-check: ✅ passpnpm run lint: ✅ passpnpm run test: ✅ pass (641 tests)pnpm run build: ✅ pass (3 actions rebuilt)pnpm audit: undici advisories resolved; only pre-existing esbuild + js-yaml advisories remain (covered by PR fix(security): remediate esbuild vulnerability #2292)Note
undici 8.x requires Node.js
>=22.19.0. All actions in this repo already usenode24runtime, and the repo's own.nvmrc/package.json#enginestrack Node 24, so this is consistent with the project's Node baseline.
