Django 2.2.19 release notes

February 19, 2021

Django 2.2.19 fixes a security issue in 2.2.18.

CVE-2021-23336: Web cache poisoning via django.utils.http.limited_parse_qsl()

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. Django now includes this fix. See bpo-42967 for further details.
