Django 2.2.19 fixes a security issue in 2.2.18.
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.
