A Difference Without a Distinction: A Measurement Study of Release Trust Evidence in Package Registries
Measurement study finds that package-registry trust signals (provenance, signatures) are inconsistent and easily bypassed, undermining supply-chain defences that CRA will soon mandate.

arXiv:2606.22593v3 Announce Type: replace-cross Abstract: A stolen npm token or account lets an attacker publish a malicious version of a popular package. Such uploads skip the project's CI workflow and can lack its provenance, so since November 2025 an opt-in pnpm policy refuses any release with weaker evidence than an earlier one. Maintainers also publish backports by hand; how often the policy blocks them and which attacks it flags is unknown. We test the policy on the latest versions of 1,9
Editorial Analysis
With CRA requiring verifiable supply-chain integrity, this research exposes a gap: most registry trust evidence is either absent or trivially circumventable, leaving dependency-gating policies on shaky ground.
Audit your CI/CD pipelines for provenance-verification enforcement and mandate attestation-backed releases for all critical dependencies.
Registry trust evidence for open-source packages is weaker than assumed—a supply-chain risk that CRA compliance will force enterprises to address.
