A stored cross-site scripting (XSS) vulnerability exists on ModelAdmin views within the Wagtail admin interface.

A user with a limited-permission editor account for the Wagtail admin could potentially craft pages and documents that, when viewed by a user with higher privileges, could perform actions with that user's credentials.

The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin, and only affects sites with ModelAdmin enabled.

For page, the vulnerability is in the "Choose a parent page" ModelAdmin view, available when managing pages via ModelAdmin.

For documents, the vulnerability is in the ModelAdmin Inspect view when displaying document fields.

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.

CVE-2020-11037: Potential timing attack on password-protected private pages

This release addresses a potential timing attack on pages or documents that have been protected with a shared password through Wagtail's "Privacy" controls. This password check is performed through a character-by-character string comparison, and so an attacker who is able to measure the time taken by this check to a high degree of accuracy could potentially use timing differences to gain knowledge of the password. (This is understood to be feasible on a local network, but not on the public internet.)

CVE-2020-11001: Possible XSS attack via page revision comparison view

This release addresses a cross-site scripting (XSS) vulnerability on the page revision comparison view within the Wagtail admin interface. A user with a limited-permission editor account for the Wagtail admin could potentially craft a page revision history that, when viewed by a user with higher privileges, could perform actions with that user credentials. The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin.
