• Advisory ID: DRUPAL-SA-CONTRIB-2011-027
  • Project: Facebook Share (third-party module)
  • Version: 6.x, 7.x
  • Date: 2011-July-06
  • Security risk: Moderately critical
  • Exploitable from: Remote
  • Vulnerability: Cross Site Scripting


This module enables Drupal site administrators to add a Facebook Share button to selected content type nodes.
The module doesn't sufficiently check the override text or button size input fields on the module configuration form to prevent against an XSS exploit.
This vulnerability is mitigated by the fact that an attacker must have a role with the permission "administer facebookshare".

Versions affected

  • Drupal 6.x-1.1 and prior
  • Drupal 7.x-1.2 and prior

Drupal core is not affected. If you do not use the contributed Facebook Share module, there is nothing you need to do.
