Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Keycloak (org.keycloak:keycloak-services, which is the Maven artifact) is affected in versions before 26.2.13, from 26.3.0 before 26.4.9, and from 26.5.0 before 26.5.3. When a UMA policy covers multiple resources, updating or deleting it checks ownership only against the first resource, so a user who owns one resource can change the policy's rules on resources owned by someone else. Upgrade to 26.2.13, 26.4.9, 26.5.3, or a later fixed release.
