NVD Description

Note: Versions mentioned in the description apply only to the upstream falcoctl package and not the falcoctl package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

sigstore-go is a Go library for Sigstore signing and verification. Prior to 1.2.0, a verifier configured with WithTransparencyLog(N>1) or WithSignedCertificateTimestamps(N>1) counts verified witnesses per entry or per validation path rather than per log authority, allowing a single compromised transparency log or CT log to satisfy multi-log threshold requirements and defeat the multi-log policy. This issue is fixed in version 1.2.0.
