CVE-2026-2996

The Advanced Product Fields (Product Addons) for WooCommerce plugin for WordPress is vulnerable to Improper Input Validation in all versions up to, and including, 1.6.21. This is due to a logic flaw in the 'validate_cart_data' function. This makes it possible for unauthenticated attackers to bypass required paid addons and complete purchases at the base product price only, effectively stealing products by paying a fraction of the intended total. The vulnerability was partially patched in version 1.6.19.

Summary		(es) El plugin Advanced Product Fields (Product Addons) para WooCommerce para WordPress es vulnerable a una validación de entrada incorrecta en todas las versiones hasta la 1.6.21, inclusive. Esto se debe a un fallo lógico en la función 'validate_cart_data'. Esto hace posible que atacantes no autenticados omitan los complementos de pago obligatorios y completen compras solo al precio base del producto, robando efectivamente productos al pagar una fracción del total previsto. La vulnerabilidad fue parcheada parcialmente en la versión 1.6.19.
