Django is a high-level Python Web framework that encourages rapid
development and a clean, pragmatic design. It focuses on automating as much

could be created by anonymously accessing the
django.contrib.auth.views.logout view if it was not decorated correctly

Red Hat would like to thank the upstream Django project for reporting this
