Project: Webform [1] Date: 2020-May-13 Security risk: *Critical* 15∕25 AC:None/A:None/CI:Some/II:None/E:Theoretical/TD:All [2] Vulnerability: Access bypass

Description:  This webform module enables you to build a 'Term checkboxes' element.

The module doesn't sufficiently check term 'view' access when rendering 'Term checkboxes' elements. Unpublished terms will always appear in the 'Term checkboxes' element.

Solution:  Install the latest version:

* If you use the Webform module for Drupal 8.x, upgrade to Webform 8.x-5.12 [3]

Also see the Webform [4] project page.
