Overview
org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.
Affected versions of this package are vulnerable to Authorization Bypass Through User-Controlled Key via the ResourceService in the resource management API. An attacker can update, read, list, or delete resources they do not own by sending requests to the resource endpoints with a valid protection token. This lets a non-owner take over or inspect protected resources and disrupt other users’ resource and permission management.
Note: While the fix was back-ported to version 26.4.12, this version has not been published to Maven Central
