Status for the latest visible version.

No SLSA provenance npm registry signatures gitHead linked

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): gaearon (Dan Abramov) is a React core team member; publishing a Facebook-owned package is expected and legitimate. ai
provenance no-provenance AI (provenance): Published in 2018, before Sigstore provenance existed. Stable for this package version. ai
provenance missing-githead AI (provenance): ljharb routinely publishes from local env without gitHead; consistent pattern across his 232+ packages. ai
bogus-package bogus-package AI (bogus-package): fb and gaearon are Facebook/Dan Abramov accounts — core React maintainers, not spam. README links to React docs. ai
phantom-deps phantom-dep:loose-envify AI (phantom-deps): loose-envify is used as a browserify transform (config reference), not a direct import — phantom-dep is expected. ai
