How to fix?

Upgrade Django to version 2.2.19, 3.0.13, 3.1.7 or higher.

Overview

Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design.

Affected versions of this package are vulnerable to Web Cache Poisoning. Django contains a copy of urllib.parse.parse_qsl() which was added to backport some security fixes. A further security fix has been issued recently such that parse_qsl() no longer allows using ; as a query parameter separator by default.
