Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance missing-githead AI (provenance): Package has SLSA provenance attestation; missing gitHead reflects CI pipeline change, not a supply chain risk. ai
maintainer-change maintainer-removed AI (maintainer-change): Cloudflare org restructuring; SLSA attestation confirms legitimate CI/CD publish pipeline. ai
maintainer-change maintainer-added AI (maintainer-change): cf-npm-publish is Cloudflare's CI publish account; consistent with org-level automation. ai
provenance publisher-changed AI (provenance): Transition to GitHub Actions CI publisher with SLSA provenance; legitimate Cloudflare org CI/CD migration. ai
source-diff obfuscated-file:dist/typescript.js AI (source-diff): Bundled TypeScript compiler shipped as minified dist artifact; expected for a worker bundler package. ai
npm-metadata suspicious-initial-version AI (npm-metadata): 0.0.0 is a Cloudflare monorepo placeholder pattern; publisher is a trusted long-standing contributor. ai
bogus-package bogus-package AI (bogus-package): Stub/namespace-reservation package in @cloudflare scope from trusted publisher; structural signals are expected. ai

v0.2.1

2 findings
HIGH Missing gitHead — previous versions had it provenance

This version has no gitHead field linking it to a source commit, but previous versions did. This suggests the publish environment changed. Published by: GitHub Actions.

INFO Has SLSA provenance attestation provenance

Published via CI/CD with Sigstore attestation (predicate: https://slsa.dev/provenance/v1). This is the strongest supply chain integrity signal.

v0.2.0

INFO Has SLSA provenance attestation provenance

Published via CI/CD with Sigstore attestation (predicate: https://slsa.dev/provenance/v1). This is the strongest supply chain integrity signal.

3 findings
HIGH Publisher changed: threepointone → GitHub Actions (on 2026-04-18) provenance

This version was published by a different npm account than previous versions on 2026-04-18. This could indicate a legitimate maintainer transition or an account compromise.

HIGH New obfuscated file: dist/typescript.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.

1 finding
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.
