GitHub Advisory Database :
When a form page type is made available to Wagtail editors through the wagtail.contrib.forms app, and the page template is built using Django’s standard form rendering helpers such as form.as_p (as directed in the documentation), any HTML tags used within a form field’s help text will be rendered unescaped in the page. Allowing HTML within help text is an intentional design decision by Django;
however, as a matter of policy Wagtail does not allow editors to insert arbitrary HTML by default, as this could potentially be used to carry out cross-site scripting attacks, including privilege escalation. This functionality should therefore not have been made available to editor-level users.
The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin.
