=========================== 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 :func:`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.
