Advisory
Source description from Wordfence Intelligence, credited to vuxvinh.
The Advanced Custom Fields plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions 6.2.0 through 6.8.10. This is due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with contributor-level access and above, to perform an unauthorized action.
