The EventPrime – Events Calendar, Bookings and Tickets plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.4.9 due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update other user's booking details.
