The module doesn't sufficiently filter user-supplied text provided in the configuration settings.

Drupal core is not affected. If you do not use the contributed Varnish HTTP Accelerator Integration [4] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the Varnish module for Drupal 6.x, upgrade to Varnish 6.x-1.2 [5] * If you use the Varnish module for Drupal 7.x, upgrade to Varnish 7.x-1.0-beta2 [6] Also see the Varnish HTTP Accelerator Integration [7] project page. -------- REPORTED BY --------------------------------------------------------- * Ivo Van Geertruyen [8] of the Drupal Security Team -------- FIXED BY ------------------------------------------------------------ * Josh Koenig [9] the module maintainer * Fabian Sörqvist [10] the module maintainer * Ivo Van Geertruyen [11] of the Drupal Security Team -------- COORDINATED BY ------------------------------------------------------ * Greg Knaddison [12] of the Drupal Security Team * Ben Jeavons [13] of the Drupal Security Team -------- CONTACT AND MORE INFORMATION ---------------------------------------- The Drupal security team can be reached at security at drupal.org or via the contact form at http://drupal.org/contact [14].
