The defacement is not stored and is only present when the URL has been crafted for that purpose. Only the defacement is present, so no other site content (such as branding) is rendered.Solution: Install the latest version:

If you are using Drupal 11.1, update to Drupal 11.1.9.
If you are using Drupal 11.2, update to Drupal 11.2.8.
