A flaw was found in the Admin REST API of Keycloak, an open-source identity and access management solution. The endpoint used for deleting user credentials does not correctly check for fine-grained reset-password permissions. This allows a delegated administrator, who should be restricted from resetting passwords, to delete a user's password credentials, resulting in the user being unable to log in.
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
