Cosign
Monthly
Cosign provides code signing and transparency for containers and binaries. [CVSS 3.7 LOW]
Cosign's bundle verification mechanism fails to properly validate that embedded Rekor entries reference the correct artifact digest, signature, and public key, allowing an attacker with a compromised signing identity to forge valid bundles and bypass transparency log verification. A malicious actor could exploit this to create counterfeit signatures that pass validation checks, affecting users relying on Cosign for container and binary code signing verification. Public exploit code exists for this vulnerability; patches are available in versions 2.6.2 and 3.0.4.
