chore(security): suppress sigstore CVE-2026-48815 in npm's bundle#62
Merged
Conversation
Trivy fails the docker job on sigstore 3.1.0 (CVE-2026-48815, HIGH) at usr/lib/node_modules/npm/node_modules/sigstore — npm's own bundled provenance dependency, not project code and unreachable by package.json overrides. The image never invokes sigstore.verify() with certificateOIDs, so the bypass is not exercised. Add a targeted .trivyignore entry mirroring the existing picomatch precedent.

Summary
Add a targeted
.trivyignoreentry forCVE-2026-48815so thedockerjob's Trivy scan stops failing CI on a HIGH CVE inside npm's own bundled dependency.Motivation
Closes #61. The
dockerjob fails on every open PR and onmasterat the Trivy step — the only finding issigstore@3.1.0/CVE-2026-48815(HIGH) atusr/lib/node_modules/npm/node_modules/sigstore/package.json. That's npm's internal bundle (NodeSource Node 22 / npm 10), not project code, and unreachable bypackage.jsonoverrides — identical to the existing picomatch precedent. The image never invokessigstore.verify()withcertificateOIDs, so the (integrity-only) bypass is not exercised. This also unblocks the 6 Dependabot PRs (#55–#60), which are red solely because of this shared job.Changes
