Hello, i've just found a new xss vulnerability in phpBB 2.0.6 (i'm not 

sure but i don't think that others versions are vulnerable).

This vulnerability is located in the [url][/url] bbcode.

You can insert javascript by doing a thing like that:

[url=www.google.fr" onclick=alert('Hello')]text[/url]



You can find differents ways to steal cookies and to stay discreet, just 

put on your brain a few seconds ;-).



Actually, there is no patch available but i have warn phpBB developpers so 

i think that they will release a patch in a few days.



PS:excuse me if my english isn't perfect but i'm french ;-).
