  * Date: 2010-July 21
  * Security risk: Moderately critical

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

The Tagging module provides an alternative input widget and other features
for taxonomy terms. The module does not properly escape user-provided content
submitted to free-tagging vocabularies displayed on node previews, leading to
a Cross Site Scripting (XSS [1]) vulnerability. Any user with permission to
create or edit a node containing a free-tagging vocabulary is vulnerable to
attack.

  * Tagging module for Drupal 6.x versions prior to 6.x-2.4.

Drupal core is not affected. If you do not use the contributed Tagging [2]
module, there is nothing you need to do.
-------- SOLUTION
