CVE-2023-2422 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:7.
NVD Description
Note: Versions mentioned in the description apply only to the upstream keycloak-oauth package and not the keycloak-oauth package as distributed by RHEL.
A flaw was found in Keycloak. A Keycloak server configured to support mTLS authentication for OAuth/OpenID clients does not properly verify the client certificate chain. A client that possesses a proper certificate can authorize itself as any other client, therefore, access data that belongs to other clients.
