Detailsinfo

A vulnerability was found in Keycloak on Red Hat (the affected version is unknown). It has been rated as problematic. This issue affects an unknown code of the component Admin API Endpoint. The manipulation with an unknown input leads to a authentication by alternate name vulnerability. Using CWE to declare the problem leads to CWE-289. The product performs authentication based on the name of a resource being accessed, or the name of the actor performing the access, but it does not properly check all possible names for that resource or actor. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

A flaw was found in Keycloak. An IDOR (Broken Access Control) vulnerability exists in the admin API endpoints for authorization resource management, specifically in ResourceSetService and PermissionTicketService. The system checks authorization against the resourceServer (client) ID provided in the API request, but the backend database lookup and modification operations (findById, delete) only use the resourceId. This mismatch allows an authenticated attacker with fine-grained admin permissions for one client (e.g., Client A) to delete or update resources belonging to another client (Client B) within the same realm by supplying a valid resource ID.

It is possible to read the advisory at access.redhat.com. The identification of this vulnerability is CVE-2025-14777 since 12/16/2025. The exploitation is known to be easy. The attack may be initiated remotely. Additional levels of successful authentication are needed for exploitation. The technical details are unknown and an exploit is not publicly available.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
