It's probably worth mentioning that there's a new project to create a MediaWiki-workalike engine that runs in a Java Servlets container. It's called JAMWiki, and it's here:

    http://jamwiki.org/

I've played around with it a little and, while it's definitely Not There Yet, it's way ahead of 80% of existing Wiki engines. I'm going to be keeping an eye on it.

And amusingly, it also has at least one of the exact same XSS vulnerabilities that used to be in MediaWiki ;-)

And yes, I have reported this to them, together with PoC, at http://jamwiki.org/wiki/en/Bug_Reports#XSS

Their implementation does look interesting though.

All the best, Nick.
