CVE-2026-40946
Critical
Description
Oxia is a metadata store and coordination system. Prior to 0.16.2, 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. This vulnerability is fixed in 0.16.2.
