CriticalSummary
In Oxia before 0.16.2, the OIDC authentication provider sets SkipClientIDCheck to true, disabling the aud claim validation. This allows tokens issued for other services by the same OIDC issuer to be accepted.

Risk of unauthorized access to Oxia via tokens intended for other applications.
Recommendation
Upgrade to version 0.16.2 or later.
Original NVD description (English source)
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.
