Does this matter?

Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.

Description

The Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to and including 4.2.0. 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 'NextGEN Manage gallery' permissions and does not enforce gallery ownership or 'NextGEN Manage others gallery' permissions. This makes it possible for authenticated attackers, with Subscriber-level privileges and 'NextGEN Manage gallery' capability, to delete gallery images belonging to other users as well as their associated image files from disk when deleteImg is enabled (default).
