Source description from Wordfence Intelligence, credited to Muni Nitish Kumar Yaddala.
The Hydra Booking plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.2.1. This is due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with hydra host-level access and above, to perform an unauthorized action.
