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

The module doesn't sufficiently filter user input under in the scenario when
a webform is edited, namely the message related to character min/max counter
does not undergo sufficient filtering and thus allows execution of JavaScript
code through it.

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.
