Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): Vercel migrated publishing to GitHub Actions CI with SLSA attestation; stable pattern for this org. ai
maintainer-change maintainer-removed AI (maintainer-change): Org-wide Vercel maintainer list cleanup; not indicative of takeover given SLSA provenance and official repo. ai
maintainer-change maintainer-added AI (maintainer-change): zeit-bot is a known Vercel automation account; consistent with org CI pipeline. ai
bogus-package bogus-package AI (bogus-package): Internal Vercel tooling package; missing metadata is expected, not a spam/malware indicator. ai
provenance no-provenance AI (provenance): Vercel packages consistently published without provenance; stable false positive for this publisher. ai

v0.3.0

2 findings
HIGH Publisher changed: vercel-release-bot → GitHub Actions (on 2026-06-05) provenance

This version was published by a different npm account than previous versions on 2026-06-05. This could indicate a legitimate maintainer transition or an account compromise.

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.

v0.2.1

2 findings
HIGH Unclaimed maintainer email domain: magic.io email-domain

Maintainer email '[email protected]' uses domain 'magic.io' which has no DNS records. An attacker could register this domain to hijack the maintainer identity.

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.

v0.2.0

2 findings
HIGH Unclaimed maintainer email domain: magic.io email-domain

Maintainer email '[email protected]' uses domain 'magic.io' which has no DNS records. An attacker could register this domain to hijack the maintainer identity.

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.
