      "value": "The Gravity Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Credit Card field\u0027s \u0027Card Type\u0027 sub-field (`input_\u003cid\u003e.4`) in all versions up to, and including, 2.9.30. This is due to the `get_value_entry_detail()` method in the `GF_Field_CreditCard` class outputting the card type value without escaping, combined with `get_value_save_entry()` accepting and storing unsanitized user input for the `input_\u003cid\u003e.4` parameter. The Card Type field is not rendered on the frontend form (it is normally derived from the card number), but the backend submission parser blindly accepts it if included in the POST request. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute when an administrator views the form entry in the WordPress dashboard."

Esto se debe a que el m\u00e9todo \u0027get_value_entry_detail()\u0027 en la clase \u0027GF_Field_CreditCard\u0027 emite el valor del tipo de tarjeta sin escapar, combinado con que \u0027get_value_save_entry()\u0027 acepta y almacena entrada de usuario no saneada para el par\u00e1metro \u0027input_ id .4\u0027. El campo Tipo de Tarjeta no se renderiza en el formulario de frontend (normalmente se deriva del n\u00famero de tarjeta), pero el analizador de env\u00edo de backend lo acepta ciegamente si se incluye en la solicitud POST. Esto hace posible que atacantes no autenticados inyecten scripts web arbitrarios que se ejecutan cuando un administrador ve la entrada del formulario en el panel de WordPress."
