Users should monitor the vendor's advisory for updates. Until a fix is released, consider disabling or restricting access to the vulnerable AJAX handler to prevent exploitation.
Description
The Event Monster plugin for WordPress up to version 2.1.0 has a vulnerability where it insufficiently verifies payment data authenticity. The AJAX handler capture_payment() accepts client-supplied payment details without server-side verification or proper authorization checks. This allows unauthenticated attackers to forge payment records, mark bookings as completed, and receive valid confirmation emails with QR code tickets without paying.
