An XSS vulnerability exists in the banners.php page of PHP-Fusion 9.03.50. This can be exploited because the only security measure used against XSS is the stripping of SCRIPT tags. A malicious actor can use HTML event handlers to run JavaScript instead of using SCRIPT tags.

In PHP-Fusion 9.03.00, edit_profile.php allows remote authenticated users to execute arbitrary code because includes/dynamics/includes/form_fileinput.php and includes/classes/PHPFusion/Installer/Lib/Core.settings.inc mishandle executable files during avatar upload.

A reflected cross-site scripting (XSS) vulnerability in PHP-Fusion 7.02.07 allows remote attackers to inject arbitrary web script or HTML via the status parameter in the CMS admin panel.
