Summary
The Event Booking Manager for WooCommerce WordPress plugin before 5.3.8 does not perform an ownership or authorization check before rendering booking confirmation details, allowing unauthenticated attackers to retrieve registered attendees' personal information (full name, email address, phone number, and custom registration fields) by supplying an enumerable booking reference. Exploitation is limited to sites configured to use the Event Booking Manager for WooCommerce WordPress plugin before 5.3.8's native (non-WooCommerce) checkout, which is not the default.
