autoprefixer
Parse CSS and add vendor prefixes to CSS rules using values from the Can I Use website
Supply chain provenance
Status for the latest visible version.
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.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| semgrep | semgrep:dynamic-require | AI (semgrep): The dynamic require loads autoprefixer's own internal updater modules by index — a stable internal plugin pattern, not user-controlled input. False positive for this package. | ai | |
| dependencies | unvetted-dep:normalize-range | AI (dependencies): normalize-range is a long-standing, benign utility dependency of autoprefixer for numeric range normalization. No security concerns. | ai | |
| dependencies | unvetted-dep:num2fraction | AI (dependencies): num2fraction is a long-standing, benign utility dependency of autoprefixer used for CSS fraction calculations. No security concerns. | ai | |
| dependencies | unvetted-dep:fraction.js | AI (dependencies): fraction.js is a legitimate math library that autoprefixer uses for CSS grid fraction calculations; this is a stable, expected dependency for this package. | ai | |
| provenance | no-provenance | AI (provenance): Autoprefixer is a long-established package from a trusted maintainer; lack of Sigstore provenance is not a meaningful risk signal here. | ai |
