# Django 3.1.7 release notes

February 19, 2021

Django 3.1.7 fixes a security issue and a bug in 3.1.6.

## 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.

## Bugfixes

- Fixed a regression in Django 3.1 that caused `RuntimeError` instead of connection errors when using only the `'postgres'` database (#32403).
