The Iubenda Integration module provides a custom block to provide a link to the Iubenda privacy policy. On this block, a custom prefix and suffix text can be entered.

This vulnerability is mitigated by the fact that an attacker must have a role with permission to use the layout builder on content, edit the layout, or with the "Administer blocks" permission.
