Estado: ModificadaMedia (6.1)—

La página de error message-page.jsp empleó el valor de la cabecera de petición HTTP X-ProxyContextPath sin sanear, lo que resulta en un ataque Cross-Site Scripting (XSS). Mitigación: La solución para analizar correctamente y sanear el valor del atributo de petición se aplicó en la distribución 1.8.0 de Apache NiFi. Los usuarios que ejecuten una distribución 1.x anterior deben actualizarla a la distribución adecuada.
