      "value": "The Ninja Forms - Excel Export plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.3.6. This is due to the save_filter() AJAX handler storing the raw $_POST['filter'] array into a WordPress option via update_option() without any capability check, nonce verification, or input sanitization, combined with the get_filter_row() method on the admin Excel Export screen concatenating the stored filter values (field_key, condition, value) directly into HTML attributes without esc_attr(). This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page."

      "value": "El plugin Ninja Forms - Excel Export para WordPress es vulnerable a cross-site scripting almacenado en versiones hasta la 3.3.6, inclusive. Esto se debe a que el gestor AJAX save_filter() almacena el array parámetro  sin procesar en una opción de WordPress a través de update_option() sin ninguna comprobación de capacidad, verificación de nonce o saneamiento de entrada, combinado con el método get_filter_row() en la pantalla de administración de exportación a Excel que concatena los valores de filtro almacenados (field_key, condition, value) directamente en atributos HTML sin esc_attr(). Esto hace posible que atacantes autenticados, con acceso de nivel de suscriptor y superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada."
