Description
ZoneMinder before 1.38.4 fails to apply per-monitor access restrictions in the FramesController index endpoint. Authenticated users with Events view permission can call the frames API to list frame records from monitors they are denied access to, disclosing event and frame metadata across monitor boundaries.
