CVE-2025-11517

The Event Tickets and Registration plugin for WordPress is vulnerable to payment bypass in all versions up to, and including, 5.26.5. This is due to the /wp-json/tribe/tickets/v1/commerce/free/order endpoint not verifying that a ticket type should be free allowing the user to bypass the payment. This makes it possible for unauthenticated attackers to obtain access to paid tickets, without paying for them, causing a loss of revenue for the target.

Summary		(es) El plugin Event Tickets and Registration para WordPress es vulnerable a una omisión de pago en todas las versiones hasta la 5.26.5, inclusive. Esto se debe a que el endpoint /wp-json/tribe/tickets/v1/commerce/free/order no verifica que un tipo de entrada deba ser gratuito, lo que permite al usuario omitir el pago. Esto hace posible que atacantes no autenticados obtengan acceso a entradas de pago, sin pagar por ellas, lo que provoca una pérdida de ingresos para el objetivo.
