Webform is the module for making surveys, petitions, contests, personalized contact forms, and the like in Drupal.
The module doesn’t sufficiently sanitize component names when components are used to determine the e-mail addresses that may be sent upon webform submission.
This vulnerability is mitigated by the fact that an attacker must have a role with permission to create/update nodes with an attached webform and (in 7.x-4.x releases) have the permission “edit webform components”.
Drupal core is not affected. If you do not use the contributed Webform module, there is nothing you need to do.
