As others have said:
php-nuke is full of risks and vulnerabilities. It's quite scary actually. I've been hit myself with a couple of attempts. It's not really the "version" but the fact that this is actually some pretty damn scary code. I did find Sentinel to provide a bit more security for phpnuke (I run a game that is rather embedded into it, so not using it isn't an option currently).
As someone else mentioned, phpnuke.org is the main site, not php-nuke.
