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
semgrep semgrep:env-spread AI (semgrep): env-spread is intentional: passes current env to spawned binary subprocess, standard launcher pattern. ai
semgrep semgrep:child-process-import AI (semgrep): child_process used solely to spawn the platform-specific binary; expected for a binary distribution wrapper. ai
semgrep semgrep:dynamic-require AI (semgrep): Dynamic require loads optional platform-specific binary packages by name; standard pattern for cross-platform binary distribution. 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.
