      "value": "The Event Monster \u2013 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 \u2014 including transaction ID, amount, and payment status \u2014 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."

Esto se debe a que el gestor AJAX capture_payment() (registrado a trav\u00e9s de wp_ajax_nopriv_em_capture_payment) conf\u00eda en los datos de pago proporcionados por el cliente - incluyendo el ID de transacci\u00f3n, el importe y el estado del pago - sin realizar ninguna verificaci\u00f3n del lado del servidor contra la API de PayPal o cualquier otra pasarela de pago, y sin comprobaciones de nonce o de capacidad. Esto permite a atacantes no autenticados falsificar registros de pago, marcar reservas como \u0027Completadas\u0027 y obtener correos electr\u00f3nicos de confirmaci\u00f3n que contienen tickets con c\u00f3digo QR v\u00e1lidos sin realizar ning\u00fan pago real."
