The Site Banner module enables you to display a banner at the top and bottom of a Drupal site.
This module incorrectly prints existing context settings without proper sanitization, opening a Cross Site Scripting (XSS) vulnerability.
This vulnerability is mitigated by the fact that an attacker must have a role with the permission “Administer contexts” from the Context UI module.
Drupal core is not affected. If you do not use the contributed module,
there is nothing you need to do.
