Who should care

System administrators and security professionals responsible for Keycloak deployments, especially those using the Admin REST API for client secret management, should be aware of this vulnerability. Reviewing and applying necessary patches or mitigations is crucial to prevent potential credential exposure.

Technical summary

A flaw in the Keycloak Admin REST API, used for managing security realms and clients, allows a delegated administrator with view-only permissions to retrieve actual resolved secrets from a secure vault. This occurs due to improper boundary enforcement when processing requests for rotated client secrets. The exposure of sensitive credentials can lead to security breaches. The issue is related to the handling of client secrets in a secure vault and the improper enforcement of access controls for delegated administrators. This vulnerability can be mitigated by reviewing and applying vendor-provided patches or updates, ensuring that delegated administrators have only necessary permissions, and implementing additional monitoring and logging for API requests related to client secret retrieval.

Defensive priority

Medium-priority defensive actions are recommended due to the potential exposure of sensitive credentials. Review and verify Keycloak Admin REST API configurations, especially those related to client secret management and vault usage.
