PHPChain contains a flaw that allows a remote Cross-Site Scripting
attacks.Input passed to the "catid" parameter in "settings.php" and in
"cat.php" isn't properly sanitised before being returned to the user.
This can be exploited to execute arbitrary HTML and script code in a
user's browser session in context of an affected site.

Also there is full path disclosure , "attacker" will get full
