Provenance

Supply chain provenance

Status for the latest visible version.

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
install-scripts install-script:postinstall AI (install-scripts): Standard prebuilt-binary install pattern for a CLI tool; stable across versions. ai
semgrep semgrep:env-spread AI (semgrep): Spreads env to invoke npm for optional dep install; intentional and benign. ai
semgrep semgrep:child-process-import AI (semgrep): Used to shell out to npm for binary install; expected for CLI installer. ai
typosquat typosquat.levenshtein:yup AI (typosquat): Scoped @bufbuild/buf is not a typosquat of 'yup'; false positive. ai

LOW No provenance attestation provenance

Package was published without Sigstore provenance. Only ~12% of npm packages have provenance, so this is common but not ideal.
