Original NVD Description
MCO does not properly enforce authorization checks in the /customer/servlet/mco/webapi/admin-view-hierarchy/get-acl-tree-structure endpoint. An authenticated, low-privileged user can retrieve administrator access control structures without proper authorization checks. This may expose sensitive permission mappings and internal configuration details. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 25.3.3.1 but may also affect other versions.
