Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design.

Affected versions of this package are vulnerable to HTTP Header Injection. In Python 3.9.5+ urllib.parse() automatically removes ASCII newlines and tabs from URLs. Unfortunately it created an issue in the URLValidator. URLValidator uses urllib.urlsplit() and urllib.urlunsplit() for creating a URL variant with Punycode which no longer contains newlines and tabs in Python 3.9.5+. As a consequence, the regular expression matched the URL (without unsafe characters) and the source value (with unsafe characters) was considered valid.

This issue was introduced by the bpo-43882 fix.
