Gitsign is a keyless Sigstore to signing tool for Git commits with your a GitHub / OIDC identity. Prior to 0.16.0, gitsign verify and gitsign verify-tag re-encode commit/tag objects through go-git's EncodeWithoutSignature before checking the signature, instead of verifying against the raw git...

webpki: Name constraints for URI names were incorrectly accepted

Name constraints for URI names were ignored and therefore accepted. Note this library does not provide an API for asserting URI names, and URI name constraints are otherwise not implemented. URI name constraints are now rejected unconditionally. Since name constraints are restrictions on otherwis...

CVE-2026-39984

CVE-2026-39984 – Sigstore Timestamp Authority (tsa/timestamp-authority/v2/pkg/verification) : Versions 2.0.5 and earlier contain an authorization bypass in VerifyTimestampResponse. The code validates the certificate chain correctly but applies TSA-specific constraints using the first non-CA certi...

Name constraints were accepted for certificates asserting a wildcard name

Permitted subtree name constraints for DNS names were accepted for certificates asserting a wildcard name. This was incorrect because, given a name constraint of accept.example.com, .example.com could feasibly allow a name of reject.example.com which is outside the constraint. This is very simila...
