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
provenance publisher-changed AI (provenance): ljharb is explicitly listed as a contributor in package.json; this is a documented, legitimate maintainer transition from tarruda. ljharb has a strong track record (2847 approved packages). ai
typosquat typosquat.levenshtein:hapi AI (typosquat): `has` is a distinct, well-established utility package with no relation to `hapi`; Levenshtein distance of 2 on a 3-char name is not meaningful typosquatting. ai
typosquat typosquat.levenshtein:qs AI (typosquat): `has` is a distinct, well-established utility package with no relation to `qs`; Levenshtein distance of 2 on short names is not meaningful typosquatting. ai
bogus-package bogus-package AI (bogus-package): `has` is a legitimate micro-utility; tiny payload and inflated semver are expected characteristics of this historically published package. ai
