Description : MISP's UiBeta theme collection view (app/View/Themed/UiBeta/Collections/view. ctp) performed a secondary query of member events by UUID without applying the caller's access control list (ACL). The CollectionsController::view() action correctly resolved collection element UUIDs through Event::fetchSimpleEvents($user, ...) , which enforces per-user event ACL.
However, the view template independently re-queried the same UUIDs using only an Event. uuid IN (...) condition, omitting the createEventConditions() authorization filter.
