[security-news at drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2011-018
  * Project: Node Reference URL Widget [1] (third-party module)
  * Version: 6.x, 7.x
  * Date: 2011-April-27
  * Security risk: Moderately critical (definition of risk levels) [2]
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting

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

The Node Reference URL Widget module adds a new widget to the Node Reference
field type, allowing node reference fields to be auto-populated based on a
value from the URL.

The module does not sanitize some of the user-supplied data before displaying
it, leading to a Cross Site Scripting (XSS [3]) vulnerability that may lead
to a malicious user gaining full administrative access.

  * Node Reference URL Widget module for Drupal 6 prior to 6.x-1.10.
  * Node Reference URL Widget module for Drupal 7 prior to 7.x-1.10.

Drupal core is not affected. If you do not use the contributed Node Reference
URL Widget [4] module, there is nothing you need to do.

-------- SOLUTION
