### Impact A cross-site scripting (XSS) vulnerability exists 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's credentials. The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin. ### Patches Patched versions have been released as Wagtail 2.7.2 (for the LTS 2.7 branch) and Wagtail 2.8.1 (for the current 2.8 branch). ### Workarounds Site owners who are unable to upgrade to the new versions can disable the revision comparison view by adding the following URL route to the top of their project's `urls.py` configuration: from django.views.generic.base import RedirectView urlpatterns = [ url(r'^admin/pages/(\d+)/revisions/compare/', RedirectView.as_view(url='/admin/')), # ... ] ### Acknowledgements Many thanks to Vlad Gerasimenko for reporting this issue. ### For more information If you have any questions or comments about this advisory: * Visit Wagtail's [support channels](https://docs.wagtail.io/en/stable/support.html) * Email us at [[email protected]](mailto:[email protected]) (if you wish to send encrypted email, the public key ID is `0x6ba1e1a86e0f8ce8`)
