TL;DR

Django's check_for_language helper caches each checked language code as a key in an in-memory translation cache. When the set_language view is routed, externally supplied POST data can submit many distinct, very long language codes that are retained as cache keys and consume process memory. This enables a denial-of-service condition, though the impact is bounded by the request size limit and the cache's maximum entry count. The fix rejects language codes longer than 500 characters before the cached lookup.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range and your application explicitly routes the django.views.i18n.set_language view.

Background info

Django is vulnerable to Denial of Service (DoS) in versions 5.2.0 - 5.2.16 and 6.0.0 - 6.0.7.
