Summary
UDS Identity Config has a client authentication bypass in `ClientIdAndKubernetesSecretAuthenticator`
Details

UDS Identity Config builds the Keycloak configuration image (realm, plugins, theme, truststore, JARs) consumed by UDS Core's Identity deployment. In versions 0.11.0 through 0.26.0, a logic error in the client-kubernetes-secret Keycloak client authenticator (shipped by uds-identity-config and consumed by UDS Core) causes the submitted client_secret to be overwritten with the mounted Kubernetes secret before comparison. An attacker who can reach the Keycloak token endpoint and knows a client_id using this authenticator can authenticate as that client with any client_secret value and obtain OAuth2 tokens scoped to the client's service account. In the case of the uds-operator client this token can be used to registry/modify other clients. Version 0.26.1 patches the issue.
