GHSA-fhvp-9hcj-6m33: Oxia has an OIDC token audience validation bypass via SkipClientIDCheck

April 14, 2026

The OIDC authentication provider unconditionally sets SkipClientIDCheck: true in the go-oidc verifier configuration, disabling the standard audience (aud) claim validation at the library level. This allows tokens issued for unrelated services by the same OIDC issuer to be accepted by Oxia.
