How to fix?

Upgrade org.keycloak:keycloak-services to version 21.1.2 or higher.

Overview

org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.

Affected versions of this package are vulnerable to Improper Certificate Validation for OAuth/OpenID clients. When a Keycloak server is configured to support mTLS authentication for OAuth/OpenID clients, it does not properly verify the client certificate chain. A client with a proper certificate can authorize itself as any other client and, therefore, access data belonging to other clients.
