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
source-diff obfuscated-file:dist/index.js AI (source-diff): dist/index.js is a lezer-generator + rollup build artifact. Long lines are bundled parser tables/logic, not obfuscation. This is the standard distribution pattern for all @lezer/* packages. ai
bogus-package bogus-package AI (bogus-package): Focused parser library in the lezer ecosystem; minimal README and no keywords are consistent with the package's narrow, well-defined purpose. ai
phantom-deps phantom-dep:@lezer/common AI (phantom-deps): @lezer/common is a legitimate peer/runtime dep in the Lezer ecosystem; not being directly imported in the detected sense is expected for grammar packages exposing types. ai
typosquat typosquat.levenshtein:nuxt AI (typosquat): @lezer/rust is a scoped Lezer parser package with no relation to nuxt; Levenshtein distance match is a clear false positive for this package. ai
typosquat typosquat.levenshtein:jest AI (typosquat): @lezer/rust is a scoped Lezer parser package with no relation to jest; Levenshtein distance match is a clear false positive for this package. ai

HIGH New obfuscated file: dist/index.js source-diff

Newly added source file contains lines over 3000 chars, suggesting minified or obfuscated code. New obfuscated files are a strong attack indicator.

LOW No provenance attestation provenance

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