Wagtail 2.9 release notes¶
What’s new¶
Report data exports¶
Data from reports, form submissions and ModelAdmin can now be exported to both XLSX and CSV format. For ModelAdmin, this is enabled by specifying a list_export
attribute on the ModelAdmin class. This feature was developed by Jacob Topp-Mugglestone and sponsored by The Motley Fool.
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.)
Many thanks to Thibaud Colas for reporting this issue.

Upgrade considerations¶
Removed support for Django 2.1¶
Django 2.1 is no longer supported as of this release; please upgrade to Django 2.2 or above before upgrading Wagtail.
SiteMiddleware
and request.site
deprecated¶
Wagtail’s SiteMiddleware
, which makes the current site object available as the property request.site
, is now deprecated as it clashes with Django’s sites framework and makes unnecessary database queries on non-Wagtail views. References to request.site
in your code should be removed; the recommended way of retrieving the current site is Site.find_for_request(request)
in Python code, and the {% wagtail_site %}
tag within Django templates. Once these are removed, 'wagtail.core.middleware.SiteMiddleware'
can be removed from your project’s MIDDLEWARE
setting.
Page / Collection managers no longer expose a delete
method¶
For consistency with standard Django models, the delete()
method is no longer available on the default Page and Collection managers. Code such as Page.objects.delete()
should be changed to Page.objects.all().delete()
.
