  "title": "sigstore-go: sigstore-go is a Go library for Sigstore signing and verification",
  "description": "sigstore-go is a Go library for Sigstore signing and verification. Prior to 1.2.0, a verifier configured with WithTransparencyLog(N\u003E1) or WithSignedCertificateTimestamps(N\u003E1) 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.",
