 "title": "Events Manager – Calendar, Bookings, Tickets, Appointments and more! <= 7.4.10 - Authenticated (Contributor+) Insecure Direct Object Reference to Booking Takeover",
 "description": "The Events Manager plugin for WordPress is vulnerable to Insecure Direct Object Reference via the booking_add action in all versions up to, and including, 7.4.10. This is due to the handler loading an existing booking from the user-supplied booking_id and then letting EM_Booking::get_post() reassign it to the event_id in the request, while the only authorization check, in EM_Booking::save(), is made against that new event. This makes it possible for authenticated attackers with contributor-level access and above who own a published event to move another user's booking onto their own event and then view the booker's personal details.",
