In Django 2.2 before 2.2.25, 3.1 before 3.1.14, and 3.2 before 3.2.10, HTTP requests for URLs with trailing newlines could bypass upstream access control based on URL paths.

Affected: Ubuntu:20.04:LTS: python-django

Sjoerd Job Postmus and TengMA discovered that Django incorrectly handled URLs with trailing newlines. A remote attacker could possibly use this issue to bypass certain access controls.
