- -------- DESCRIPTION ---------------------------------------------------------
The Node Reference URL Widget module adds a new widget to the Node Reference

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 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 ------------------------------------------------------------

* If you use the Node Reference URL Widget module for Drupal 6.x upgrade to
Node Reference URL Widget 6.x-1.10 [5].
