Overview
Affected versions of this package are vulnerable to Improper Authentication in the OIDC authenticator. An attacker can gain access to the API by presenting a JWT that a shared identity provider issued for an unrelated service, because the token's audience (aud) claim is not validated. This applies only when authn.method is set to oidc with authn.oidc.issuer configured but authn.oidc.audience left unset, in an environment where a common identity provider issues tokens for multiple services.
