Source description from Wordfence Intelligence, credited to genisis-lab.
The Event Post plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 6.1.1. 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.
