Supply chain provenance

Status for the latest visible version.

No SLSA provenance npm registry signatures No source commit

Accepted risks

Findings the reviewer chose to accept rather than block on.

Source	Rule	Reason	Accepted by	When
bogus-package	bogus-package	AI (bogus-package): Internal Vercel tooling package; missing metadata is expected, not a spam/malware indicator.	ai	2026/05/16
provenance	no-provenance	AI (provenance): Vercel packages consistently published without provenance; stable false positive for this publisher.	ai	2026/05/16

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.
