The Eventin – Event Calendar, Event Registration, Tickets & Booking (AI Powered) plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.1.22. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to bypass payment for paid events, fraudulently mark orders as completed, deplete ticket inventory, and trigger confirmation emails for tickets never purchased. This is exploitable by unauthenticated attackers because the wp_rest nonce is publicly emitted on every frontend page, and the order creation endpoint mints and returns an order_access_token to any caller possessing that nonce — giving unauthenticated users all credentials required to reach the privileged update_booking_status branch.
