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:etc-passwd-access AI (semgrep): The /etc/passwd read is in test.js as a demonstration of parallel file reading — a canonical example for this control-flow library, not credential harvesting. ai
semgrep semgrep:dynamic-require AI (semgrep): require(__dirname + '/lib/step') is a standard Node.js local module require pattern, not a dynamic/arbitrary module load. ai
provenance no-provenance AI (provenance): Package is 5540 days old, predating Sigstore provenance by many years. Absence is expected and not a risk signal. ai
