• Advisory ID: DRUPAL-SA-CONTRIB-2012-119
  • Project: Excluded Users (third-party module)
  • Version: 6.x
  • Date: 2012-August-1
  • Security risk: Less critical
  • Exploitable from: Remote
  • Vulnerability: Cross Site Scripting


Excluded Users is a helper module which allows administrators to select users to not appear in user listings.

The module displays a list of user names and email addresses without sanitizing them. In the event that someone manages to insert malicious code into a user name or email address, this might lead to an XSS attack.

This vulnerability is mitigated by the fact that the user name and email address are validated on creation by default but other user creation methods could create a vulnerability.
