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
bogus-package bogus-package AI (bogus-package): Established @lezer ecosystem package by Marijn Haverbeke; README/keywords signals are cosmetic and the inflated semver flag is a false positive for a package with 12 versions over 4+ years. ai
dependencies unvetted-dep:@lezer/lr AI (dependencies): @lezer/lr is a first-party dependency in the same @lezer ecosystem, authored by the same publisher (Marijn Haverbeke). Not a risk. ai
source-diff obfuscated-file:dist/index.js AI (source-diff): dist/index.js is a lezer-generator output file with rollup bundling; long lines are serialized parse tables, not obfuscation. Stable pattern for all @lezer/* packages. ai
typosquat typosquat.levenshtein:pg AI (typosquat): @lezer/cpp is a scoped package in the lezer-parser ecosystem; Levenshtein match to 'pg' is a false positive with no impersonation intent. ai
typosquat typosquat.levenshtein:yup AI (typosquat): @lezer/cpp is a scoped package in the lezer-parser ecosystem; Levenshtein match to 'yup' is a false positive with no impersonation intent. ai
phantom-deps phantom-dep:@lezer/common AI (phantom-deps): @lezer/common is a legitimate peer/indirect dependency within the same @lezer org scope; not a security concern for this grammar package. ai

v1.1.6

1 finding
LOW No provenance attestation provenance

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

v1.1.4

1 finding
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.
