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/denis-sokolov AI (email-domain): The 'email' field is a GitHub profile URL, not an email address. The analyzer is misinterpreting it as a domain. No real hijack risk; stable false positive for this DefinitelyTyped package. ai
bogus-package bogus-package AI (bogus-package): @types/* packages are inherently tiny, have no runtime deps, and skip keywords — these signals are expected for TypeScript definition packages from DefinitelyTyped. ai

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

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