Technical details

Missing access-control checks on PUT/DELETE /action/{id} endpoints allow authenticated users to modify or delete Layout actions without ownership validation. An authenticated user with standard privileges (which includes edit permissions on all layouts by default) can exploit this to alter or remove actions from any layout via API calls without authorization. The fix adds AccessDeniedException checks to enforce ownership verification.
