  * Version: 5.x, 6.x
  * Date: 2009-March-25

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

The Vote Up/Down module provides a voting widget for content that records
votes using Ajax. The URL for voting is vulnerable to cross-site request
forgeries (CSRF [1]) making it possible for users to unknowingly vote for

  * Vote Up/Down 6.x-1.x prior to 6.x-1.0-beta4

Drupal core is not affected. If you do not use the contributed Vote Up/Down
module, there is nothing you need to do.
-------- SOLUTION
