CyberRota Analysis
AI-GeneratedThe sigstore-go library, prior to version 1.2.0, is vulnerable due to a flaw in its verification process, which allows a single compromised transparency log to meet the multi-log threshold requirements, undermining the integrity of the multi-log policy. This could lead to unauthorized signing and verification of artifacts, potentially impacting the security of software supply chains. Organizations utilizing sigstore-go for signing and verification should prioritize upgrading to version 1.2.0 to mitigate this vulnerability.

Original NVD Description
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.
