Description

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.
