Project: GOV.UK Theme [1]
Date: 2022-February-23
Security risk: *Moderately critical* 14∕25
AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:All [2]
Vulnerability: Cross site scripting

Description: 
The GOV.UK Theme (govuk_theme) is a Drupal theme for the GOV.UK Design
System.

The theme doesn't sanitize user input in certain cases, which leads to
Cross-Site-Scripting (XSS) vulnerabilities. An attacker that can create or
edit certain entities or configuration may be able to exploit one or more
Cross-Site-Scripting (XSS) vulnerabilities to target visitors of the site,
including site admins with privileged access.

The vulnerability is mitigated by the facts, that:

  * An attacker must have one of several permissions, of which at least some
    are commonly only assigned to either editors, site builders or
    administrators.
  * For some of the vulnerabilities, certain contributed modules must be
    enabled.

Solution: 
Install the latest version:

  * If you use the govuk_theme for Drupal 9.x, upgrade to govuk_theme 8.x-1.9
