Event Monster <= 2.1.0 - Unauthenticated Insufficient Verification of Data Authenticity to Payment Bypass via em_capture_payment AJAX Action

Event Monster – Event Manager, Event Booking, Event Ticket & Registration: Currently marked unpatched

Affected versions: *-2.1.0

Vulnerability type: CWE-345 Insufficient Verification of Data Authenticity

Affected software, patched versions and attribution

The Event Monster – Event Management, Events Calendar, Tickets plugin for WordPress is vulnerable to Insufficient Verification of Data Authenticity in versions up to, and including, 2.1.0. This is due to the capture_payment() AJAX handler (registered via wp_ajax_nopriv_em_capture_payment) trusting client-supplied payment data — including transaction ID, amount, and payment status — without performing any server-side verification against the PayPal API or any other payment gateway, and without nonce or capability checks. This makes it possible for unauthenticated attackers to forge payment records, mark bookings as Completed, and obtain confirmation emails containing valid QR code tickets without making any actual payment.
