DJANGO PATCHES REDIRECT LENGTH BUG AND PYTHON 3.14 TEST FAILURES

By RepoJournal · Filed · About Django

Django shipped fixes for a percent-encoded redirect length vulnerability and Python 3.14 compatibility issues that were breaking test suites.

The core fixes land in django/django this cycle: a critical redirect length check [1] now validates against percent-encoded URLs (catching bypass attempts that rely on encoding tricks), and a test compatibility fix [2] resolves failures on Python 3.14.5+ caused by upstream cpython changes. Documentation also got a clarification [3] on why setting model fields doesn't auto-convert types — a common source of subtle bugs. The redirect fix is the one to watch: it closes a security gap in how Django validates max_length on redirects, and teams relying on that validation should verify their implementations handle encoded URLs correctly. Over on djangoproject.com, dependency updates [4] [5] rolled through: requests 2.33.1 cleans up test artifacts from CVE work, and django-debug-toolbar 6.3.0 shipped new improvements. These are routine maintenance — no breaking changes.
