 "title": "Events Manager – Calendar, Bookings, Tickets, Appointments and more! <= 7.4.12 - Unauthenticated Insecure Direct Object Reference to Booking Withdrawal Declaration",
 "description": "The Events Manager plugin for WordPress is vulnerable to Insecure Direct Object Reference via the right-of-withdrawal form ([em_withdrawal_form]) lookup, select and confirm steps in versions 7.3.6 up to, and including, 7.4.12. This is due to the plugin accepting a sequential booking ID as the booking reference and trusting the booking ID and email address posted in form fields, instead of requiring the unguessable booking UUID or a verified emailed link. This makes it possible for unauthenticated attackers who know a booking's email address to file withdrawal declarations on other users' bookings, when the withdrawal feature is enabled.",
