Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Keycloak's org.keycloak:keycloak-services package is affected in versions before 24.0.5. A user with low privileges in a realm, such as an ordinary user with no admin role, can use administrative functions in the Keycloak admin API, which the source says could lead to data breaches or system compromise. Upgrade keycloak-services to version 24.0.5 or later. The source gives few details on the exact requests or conditions involved.
