# Django 3.0.13 release notes

February 19, 2021

Django 3.0.13 fixes a security issue in 3.0.12.

## 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.
