PHPFusion 9.10.30 contains a stored cross-site scripting vulnerability in the file manager that allows attackers to upload malicious SVG files with embedded JavaScript. Attackers can upload SVG files with script tags that execute arbitrary JavaScript when viewed, potentially stealing user session information or performing client-side attacks.

PHPFusion 9.03.50 contains a persistent cross-site scripting vulnerability in the print.php page that fails to properly sanitize user-submitted message content. Attackers can inject malicious JavaScript through forum messages that will execute when the print page is generated, allowing script execution in victim browsers.
