• Advisory ID: DRUPAL-SA-CONTRIB-2013-080
  • Project: Simplenews (third-party module)
  • Version: 6.x, 7.x
  • Date: 2013-Month-DD
  • Security risk: Moderately critical
  • Exploitable from: Remote
  • Vulnerability: Cross Site Scripting


This module enables you to publish and send newsletters to lists of subscribers.
The module also includes an API that other modules can use to register subscribers.
The module doesn't sufficiently sanitize e-mail addresses prior to outputting. The provided forms (sign-up, mass import, ..) validate and only allow valid e-mail addresses, but e-mail addresses could also be added directly through the API, which does not validate.

This vulnerability is mitigated by the fact that the Simplnews module performs input validation which prevents known attacks, so the injection vector must be added another module (custom or contributed) without validating the email address using the Simplenews API .
