Los formularios de pago, los botones "Comprar ahora" y el sistema de facturación del plugin GetPaid para WordPress son vulnerables a Stored Cross-Site Scripting (XSS almacenado) a través del parámetro 'mmdwqzpoxadd' en todas las versiones hasta la 2.8.61 inclusive, debido a un saneamiento de la entrada y un escape de la salida insuficientes. Esto permite que atacantes sin autenticar inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada.

Leer descripción completaMostrar menos

El nonce requerido (getpaid_form_nonce) se emite públicamente a todos los visitantes mediante wp_localize_script como WPInv.formNonce, lo que significa que no se necesita autenticación ni una filtración previa del nonce; el payload almacenado se activa cuando un administrador consulta el metabox "Payment Form Details" de la factura afectada.

This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The required nonce (getpaid_form_nonce) is publicly emitted to all visitors via wp_localize_script as WPInv.formNonce, meaning no authentication or prior nonce leak is needed; the stored payload fires when an administrator views the affected invoice's Payment Form Details metabox."
