The vulnerability stems from improper ACL enforcement when backend controllers are accessed via specific URL patterns. The root cause likely involves: (1) The preDispatch method in backend controllers (where ACL checks are typically enforced) failing to handle non-standard controller/action parameter formats, allowing bypass via crafted URLs. (2) The ACL system's controller/action resolution logic not properly normalizing input parameters, causing mismatches between requested resources and permission checks. The high confidence in AbstractController::preDispatch stems from its role as the primary ACL enforcement point, while the medium confidence in Acl::isAllowed reflects potential normalization flaws in permission mapping.
