Provenance

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.

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
email-domain unclaimed-email:https://github.com/reppners AI (email-domain): The 'email' is actually a GitHub URL used as author contact per DT convention; not a real email domain. No hijack risk. ai
bogus-package bogus-package AI (bogus-package): @types/* packages are inherently tiny .d.ts files with no deps or keywords; all three signals are expected for DefinitelyTyped. ai

HIGH Unclaimed maintainer email domain: https://github.com/reppners email-domain

Maintainer email 'https://github.com/reppners' uses domain 'https://github.com/reppners' which has no DNS records. An attacker could register this domain to hijack the maintainer identity.

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.
