Medium severity, CVSS 4.9. EPSS: 0.2% chance of exploitation in the next 30 days.

A flaw was found in the installation provider and client registration endpoints of the Keycloak identity management service.

This exposed secret can be used to impersonate the client and gain unauthorized access to its associated service account permissions.
