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

The Fivestar module enables you to add a voting widget to nodes and comments.

The module does not sufficiently validate all votes passed by the asynchronous voting widget allowing a malicious user to improperly modify voting averages.

Drupal core is not affected. If you do not use the contributed Fivestar [3] module, there is nothing you need to do.

-------- SOLUTION ------------------------------------------------------------

Install the latest version:

* If you use the Fivestar module for Drupal 6.x, upgrade to Fivestar 6.x-1.20 [4]

Also see the Fivestar [5] project page.
