Supply chain provenance

Status for the latest visible version.

No SLSA provenance npm registry signatures No source commit

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.

v2.1.0

3 findings
HIGH Missing gitHead — previous versions had it provenance

This version has no gitHead field linking it to a source commit, but previous versions did. This suggests the publish environment changed. Published by: boneskull.

LOW No provenance attestation provenance

Package was published without Sigstore provenance. Consider requesting the maintainer enable provenance via CI/CD.

INFO Publisher changed: mhofman → boneskull (on 2026-05-27, known maintainer) provenance

This version was published by a different npm account (boneskull) than the most recent previously approved version (mhofman) on 2026-05-27, but boneskull is listed as a maintainer on prior approved versions (matched on name). This looks like a manual publish by a known maintainer rather than a publisher change. Recorded as INFO for audit trail.
