XSS Vulnerability in BBCodeItem
Google/translate2Thank You!0Good Post!1Bad Post! link
As most of you should know, a part of the cookie is a lie challenge consists of sending a PM to Z which he will click.

Well, one user, namely hellsonic, managed to exploit the bbdecoder to automatize this task via XSS.

The flaw lied within the url parameter of the url tag, which was not sanitzed.
The problem got fixed in SVN with changeset 2271.

Big thanks and gratulations to hellsonic for finding this flaw.
Also thanks to Z for reporting the flaw Smile

Happy Challenging!
