No SLSA provenance npm registry signatures gitHead linked

Without SLSA provenance there is no cryptographic link between this tarball and the public source — the axios compromise (March 2026) relied on exactly this gap.

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance no-provenance AI (provenance): Firebase SDK packages consistently lack Sigstore provenance; this is a known gap in their publishing pipeline, not a per-version risk signal. ai
provenance publisher-changed AI (provenance): google-wombot is Google's official Firebase SDK automation publisher; publisher transitions to this account are expected and legitimate for @firebase/* packages. ai
maintainer-change maintainer-removed AI (maintainer-change): Firebase SDK maintainer roster changes over time are expected for a long-lived Google project; removal of individual maintainers is not a takeover signal here. ai
publish-pattern dormant-publish AI (publish-pattern): Dormancy signal is an artifact of comparing against a very old approved version (v0.2.6); the package has 3087 versions in registry indicating continuous active development. ai
publish-pattern new-deps-added AI (publish-pattern): web-vitals is Google's own Core Web Vitals library; @firebase/component is part of the Firebase SDK. Both are legitimate, well-established dependencies for a performance monitoring package. ai
bogus-package bogus-package AI (bogus-package): This is a legitimate Firebase SDK sub-package from Google's monorepo. Short README and missing keywords are typical for internal SDK packages, not spam indicators. ai
dependencies unvetted-dep:@firebase/util AI (dependencies): First-party Firebase SDK dependency from the same Google monorepo; not a third-party risk. ai
dependencies unvetted-dep:@firebase/logger AI (dependencies): First-party Firebase SDK dependency from the same Google monorepo; not a third-party risk. ai
dependencies unvetted-dep:@firebase/installations AI (dependencies): First-party Firebase SDK dependency from the same Google monorepo; not a third-party risk. ai
dependencies unvetted-dep:@firebase/performance-types AI (dependencies): First-party Firebase SDK dependency from the same Google monorepo; not a third-party risk. ai
