Summary		(es) PasswordPusher anterior a la versión 2.8.1 acepta esquemas URI de datos en las cargas útiles de envío de URL debido a una validación insuficiente en la función valid_url. Los atacantes pueden crear envíos maliciosos que contienen URIs data:text/html que ejecutan JavaScript arbitrario en los navegadores de las víctimas al hacer clic, lo que permite el phishing y el robo de credenciales bajo el dominio de confianza de PasswordPusher.
