This is due to insufficient object-level authorization in the image deletion REST flow where the permission callback for DELETE /imagely/v1/images/{id} only checks \u0027NextGEN Manage gallery\u0027 permissions and does not enforce gallery ownership or \u0027NextGEN Manage others gallery\u0027 permissions. This makes it possible for authenticated attackers, with Subscriber-level privileges and \u0027NextGEN Manage gallery\u0027 capability, to delete gallery images belonging to other users as well as their associated image files from disk when deleteImg is enabled (default)."
