Show the technical text from the sources
A flaw was found in the UMA resource registration endpoint of the keycloak-services component, which provides the core logic for Keycloak's authorization and identity services. The issue occurs when remote resource management is enabled, allowing an authenticated user with specific permissions to update resources they do not own by providing a target resource ID in a request. This can lead to unauthorized modification of resource configurations, such as names, URIs, and scopes.
