The module doesn't sufficiently sanitize several administrator-configured response messages (the "Yes response", "No response", and the custom text shown on a "No" answer) under the scenario where those settings contain HTML or script markup, which is then emitted as raw HTML in the feedback response shown to visitors. This vulnerability is mitigated by the fact that an attacker must have a role with the permission "administer admin feedback". Solution:  Install the latest release: * If you use the admin_feedback module for Drupal 8.x, upgrade to admin_feedback 8.x-2.8 [3] The configured plain-text responses are now escaped with `Html::escape()`, and the formatted "No" response is rendered through its configured text format filter (`check_markup()`) instead of being printed raw.
