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

The Fivestar module provides a voting widget for content and records votes
using Ajax. The URL used by the javascript to register votes is vulnerable to
cross-site request forgeries (CSRF [1]) making it possible for users to
unknowingly vote for content.

  * Fivestar 6.x-1.x prior to 6.x-1.14

Drupal core is not affected. If you do not use the contributed Fivestar
module, there is nothing you need to do.
