Project: Webform [1]
Date: 2020-May-06
Security risk: *Moderately critical* 13∕25
AC:Basic/A:Admin/CI:Some/II:Some/E:Theoretical/TD:All [2]
Vulnerability: Cross site scripting

Description: 
The Webform module allows site builders to create forms.

The module doesn't sufficiently prevent malicious code from being render via
an options elements (i.e select menu, checkboxes, radios, etc...) under the
scenario where the site builder allows the raw option value to be displayed.

This vulnerability is mitigated by the fact that site builder must be allowed
to build webform and select raw as the options element's submission display.

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.
