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): Standard esbuild/tsup bundle output with CJS interop helpers; dependencies bundled inline rather than declared as runtime deps. ai
source-diff obfuscated-file:dist/index.mjs AI (source-diff): ESM counterpart of the tsup bundle; same bundled dependencies pattern, not obfuscation. ai
source-diff net-exec-file:dist/index.js AI (source-diff): Bundled @babel/parser and code generator contain dynamic patterns triggering heuristics; no actual malicious network/exec code. ai
source-diff net-exec-file:dist/index.mjs AI (source-diff): ESM bundle counterpart; same false positive from bundled babel tooling. ai
source-diff source-size-tripled AI (source-diff): Size increase is from bundling previously-external runtime deps (babel, lodash, prettier) into dist output. ai

5 findings
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.

HIGH New file with network + code execution: dist/index.js source-diff

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

HIGH New obfuscated file: dist/index.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/index.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.

LOW No provenance attestation provenance

Package was published without Sigstore provenance. Only ~12% of npm packages have provenance, so this is common but not ideal.
