  * Date: 2010-March-03

-------- DESCRIPTION  
---------------------------------------------------------

The AddThis module provides an easy way to share content to over 230
supported services such as Facebook, Email and Twitter. The module did not
sanitize some user-supplied data before displaying it, leading to a Cross

addthis' permission were able to exploit this vulnerability.

module, there is nothing you need to do.
