Summary
A flaw was found in the Dynamic Client Registration service of Keycloak, an open-source identity and access management solution. The issue occurs when a user with the view-clients role accesses the client registration endpoint to retrieve client details. Due to a failure to mask sensitive information, the service returns the client's confidential secret in cleartext. This could allow a read-only administrator to obtain full access to the affected client's account and potentially escalate their privileges within the realm.
