Advisory
Source description from Wordfence Intelligence, credited to Erwan LR.
The NextGEN Gallery plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.4.0. This is due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with admin-level access and above, to perform an unauthorized action.
