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, so a manually published version cannot be tied back to a reviewed commit.

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
vendored-integrity tampered-vendored-dep:node_modules/jsbn AI (vendored-integrity): Only differing file is jsbn/package.json (manifest); code files byte-match [email protected]. ai
source-diff encoded-string-file:fnv-plus.js AI (source-diff): Long hex strings are FNV algorithm constants (primes/offsets/masks), intrinsic to this hash library. ai
source-diff encoded-string-file:spec/fnv-plus.js AI (source-diff): Long hex strings are expected hash test vectors in the spec file. ai

v1.2.12

2 findings
HIGH Modified vendored dependency: node_modules/jsbn (1 file(s)) vendored-integrity

The directory `node_modules/jsbn` byte-matched 5 of 6 file(s) against [email protected] — a version that passed review and that we hold in storage — which identifies it as a vendored copy of that package. But 1 file(s) inside it differ from that package's bytes at the same path: node_modules/jsbn/package.json. A vendored library that is a faithful copy except for a handful of altered files is a well-worn supply-chain shape — the surrounding real code lends the tree legitimacy while the altered files carry the payload. These files are NOT exempt from any authorship heuristic; diff them against [email protected] before greenflagging.

LOW No provenance attestation provenance

Package was published without Sigstore provenance. Consider requesting the maintainer enable provenance via CI/CD.
