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 Unpublished terms will always appear in the 'Term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]
