• Advisory ID: DRUPAL-SA-CONTRIB-2009-075
  • Project: Organic Groups Vocabulary (third-party module)
  • Version: 5.x
  • Date: 2009-October-21
  • Security risk: Critical
  • Exploitable from: Remote
  • Vulnerability: Cross Site Scripting


The Organic Groups Vocabulary module enables an organic group to have a group specific vocabulary. In some specific cases, the module does not sanitize before outputting the group title, resulting in a cross-site scripting (XSS) vulnerability. Such an attack may lead to a malicious user gaining full administrative access.

Versions affected

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


Upgrade to the latest version:
