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.

Source	Rule	Reason	Accepted by	When
source-diff	obfuscated-file:dist/cli.mjs	AI (source-diff): dist/cli.mjs is a Rollup-bundled CLI entry point; long lines are standard minification output, not obfuscation. This is expected for this package's build process.	ai	2026/04/22
source-diff	net-exec-file:dist/cli.mjs	AI (source-diff): The dynamic import() in cli.mjs loads user-specified local env files (importFrom feature). No actual network calls present. False positive for this package's documented functionality.	ai	2026/04/22
source-diff	source-size-tripled	AI (source-diff): Size increase is entirely explained by the new bundled CLI (dist/cli.mjs, 86KB), a Rollup bundle that inlines dependencies. Expected for this package.	ai	2026/04/22
dependencies	unvetted-dep:postcss-value-parser	AI (dependencies): postcss-value-parser is a well-known, widely-used PostCSS utility; its use here is expected and legitimate for a PostCSS plugin.	ai	2026/04/22
semgrep	semgrep:dynamic-require	AI (semgrep): Dynamic require is intentional: the plugin loads user-specified JS environment files at runtime as a documented feature. Not a security risk in this context.	ai	2026/04/22
provenance	no-provenance	AI (provenance): Established package from a highly trusted publisher; lack of provenance attestation is not a meaningful risk signal here.	ai	2026/04/22
license	uncommon-license:MIT-0	AI (license): MIT-0 is a recognized permissive license (MIT without attribution requirement); stable for this package from the csstools org.	ai	2026/04/21
phantom-deps	phantom-dep:postcss-value-parser	AI (phantom-deps): postcss-value-parser is a legitimate declared dependency in a monorepo context; phantom-dep flag is a false positive for this package.	ai	2026/04/21

v4.0.3

3 findings

HIGH New obfuscated file: dist/cli.mjs source-diff

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

HIGH New file with network + code execution: dist/cli.mjs source-diff

Newly added file contains both network calls and dynamic code execution. This is a hallmark of dropper/loader malware.

LOW No provenance attestation provenance

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