    CVE-2026-31830 (GCVE-0-2026-31830)

    Vulnerability from nvd – Published: 2026-03-10 21:46 – Updated: 2026-03-11 15:59

    Title
    sigstore-ruby verifier returns success for DSSE bundles with mismatched in-toto subject digest
    Summary
    sigstore-ruby is a pure Ruby implementation of the sigstore verify command from the sigstore/cosign project. Prior to 0.2.3, Sigstore::Verifier#verify does not propagate the VerificationFailure returned by verify_in_toto when the artifact digest does not match the digest in the in-toto attestation subject. As a result, verification of DSSE bundles containing in-toto statements returns VerificationSuccess regardless of whether the artifact matches the attested subject. This vulnerability is fixed in 0.2.3.
