View online: https://www.drupal.org/sa-contrib-2020-011 Project: Webform [1] Date: 2020-May-06 Security risk: *Critical* 17∕25 AC:Basic/A:Admin/CI:All/II:All/E:Theoretical/TD:All [2] Vulnerability: Remote Code Execution Description:  This module enables you to build forms and surveys in Drupal. The module doesn't sufficiently filter webform element properties (attributes) under the scenario of editing a webform. Malicious user could craft such an attribute (#element_validate, for example) that would invoke execution of undesired PHP code. This vulnerability is mitigated by the fact that an attacker must have a role with the permission "Edit own webform" (or "Edit any webform"). Solution:  Install the latest version: * If you use the Webform module for Drupal 8, upgrade to Webform 8.x-5.11 [3] Also see the Webform [4] project page.
