Descriptions

The Newsletter WordPress plugin before 7.4.5 does not sanitize and escape the $_SERVER['REQUEST_URI'] before echoing it back in admin pages. Although this uses addslashes, and most modern browsers automatically URLEncode requests, this is still vulnerable to Reflected XSS in older browsers such as Internet Explorer 9 or below.

El plugin Newsletter de WordPress versiones anteriores a 7.4.5, no sanea y escapa el $_SERVER["REQUEST_URI"] antes de devolverlo en las páginas de administración. Aunque esto usa addslashes, y la mayoría de los navegadores modernos automáticamente URLEncode peticiones, esto sigue siendo vulnerable a un ataque de tipo XSS Reflejado en los navegadores más antiguos como Internet Explorer 9 o anteriores
