Description
A flaw was found in Keycloak. A realm administrator with the "manage-realm" role can exploit this vulnerability by submitting an arbitrary filesystem path as a keystore parameter when creating a key provider component. This allows the administrator to probe arbitrary filesystem paths, determining which files exist and are readable by the Keycloak process. This information disclosure could be used to identify high-value targets for follow-on attacks.

What to do
Workaround: Ensure that only highly trusted administrators are granted the "manage-realm" role within Keycloak. This role provides extensive administrative privileges, including the ability to exploit this vulnerability for filesystem probing. Regularly review and audit users assigned to this role to minimize the attack surface.
