Description

This module enables you to build forms and surveys in Drupal.

The module doesn't sufficiently sanitize Webform labels nor visibility conditions under the scenario of placing a block. When a webform block is placed and visible on a website any JavaScript code contained within the webform's label was executed.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission "Edit own webform" (or "Edit any webform").
