Change: js-yaml 4.2.0 → 4.3.1 (dev-scope, transitive) (dev dependency, lockfile-only)

Supply-chain verification

Check Result
PR author dependabot[bot]
Diff scope package-lock.json only — no source, CI, or script changes ✅
Registry npmjs.com ✅
Publisher GitHub Actions (OIDC trusted publishing) ✅
SLSA provenance https://slsa.dev/provenance/v1 present ✅
Provenance subject matches pkg:npm/<name>@<version>
Source repo matches declared repository field ✅
Install hooks no preinstall/install/postinstall

Impact

  • devDependency only — no production/runtime exposure.
  • Patch/minor bump; manifest range already permitted the new version (hence lockfile-only).
  • js-yaml 4.3.1 is a security backport — fixes quadratic complexity in !!omap duplicate-key detection. 4.x is actively maintained alongside 5.x.
  • No SLSA provenance; confidence rests on publisher continuity (vitaly, unchanged across adjacent versions), maintainer-signed source tag, small reviewable diff, and no install hooks. nodeca/js-yaml publishes no GitHub releases at all — git tags are the release mechanism, so the absent release is project convention, not an anomaly.

CI

All checks green. CodeQL: NEUTRAL is CodeQL declining to analyse a lockfile-only change (no code delta to scan) — not a failure.
