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 [3] Reported By:  * Patrick Fey [4] Fixed By:  * Andrew Hughes-Onslow [5] * Patrick Fey [6] Coordinated By:  * Chris McCafferty [7] of the Drupal Security Team [1] https://www.drupal.org/project/govuk_theme [2] https://www.drupal.org/security-team/risk-levels [3] https://www.drupal.org/project/govuk_theme/releases/8.x-1.9 [4] https://www.drupal.org/user/998680 [5] https://www.drupal.org/user/2547946 [6] https://www.drupal.org/user/998680 [7] https://www.drupal.org/user/1850070
