      "value": "The Easy Cart plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'add_to_cart' shortcode in all versions up to and including 1.8. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes. Specifically, the ectp_add_to_cart() function uses sanitize_text_field() on shortcode attributes like 'itemid', 'product_name', 'product_desc', 'product_qty', and 'price' before inserting them into double-quoted HTML attributes. While sanitize_text_field() strips HTML tags, it does not escape double quote characters, allowing an attacker to break out of the HTML attribute context and inject arbitrary event handlers. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page."

      "value": "El plugin Easy Cart para WordPress es vulnerable a Cross-Site Scripting Almacenado a través del shortcode 'add_to_cart' en todas las versiones hasta la 1.8 inclusive. Esto se debe a una sanitización de entrada y un escape de salida insuficientes en los atributos del shortcode proporcionados por el usuario. Específicamente, la función ectp_add_to_cart() utiliza sanitize_text_field() en atributos de shortcode como 'itemid', 'product_name', 'product_desc', 'product_qty' y 'price' antes de insertarlos en atributos HTML entre comillas dobles. Si bien sanitize_text_field() elimina las etiquetas HTML, no escapa los caracteres de comillas dobles, lo que permite a un atacante salir del contexto del atributo HTML e inyectar manejadores de eventos arbitrarios. Esto hace posible que atacantes autenticados, con acceso de nivel Colaborador y superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada."
