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
provenance publisher-changed AI (provenance): Maintainer transition within webpack-contrib org; evilebottnawi has strong track record (327 approved packages). ai
publish-pattern new-deps-added AI (publish-pattern): New deps (jiti, klona, semver, cosmiconfig) are all established; jiti replaces cosmiconfig-typescript-loader for config loading. ai
source-diff net-exec-file:dist/utils.js AI (source-diff): Dynamic code execution in utils.js is legitimate config loading via cosmiconfig; core functionality of webpack loaders, not malware. ai
maintainer-change maintainer-removed AI (maintainer-change): Legitimate handoff; michael-ciniawsky removed as part of org transition, not a takeover signal. ai
publish-pattern dormant-publish AI (publish-pattern): postcss-loader is an official webpack org package with a strong publisher track record; dormancy reflects stability, not abandonment. Legitimate maintenance resume. ai
semgrep semgrep:dynamic-require AI (semgrep): Dynamic require() is intentional design: postcss-loader resolves user-configured parser/syntax/stringifier plugins by name from webpack config. This is documented behavior, not arbitrary code loading. ai
maintainer-change maintainer-added AI (maintainer-change): New maintainers (evilebottnawi, sokra, jhnns) are well-known webpack-contrib contributors. Legitimate transition. ai
dependencies unvetted-dep:jiti AI (dependencies): jiti is a legitimate, transparent JavaScript transpiler widely used in build tooling; appropriate for postcss-loader's use case. ai
provenance no-provenance AI (provenance): postcss-loader is a well-established webpack org package; lack of provenance is common and not a material risk here. ai
