NVD Description

Note: Versions mentioned in the description apply only to the upstream py3-django package and not the py3-django package as distributed by Alpine. See How to fix? for Alpine:3.24 relevant fixed versions and status.

In Django 3.2 before 3.2.17, 4.0 before 4.0.9, and 4.1 before 4.1.6, the parsed values of Accept-Language headers are cached in order to avoid repetitive parsing. This leads to a potential denial-of-service vector via excessive memory usage if the raw value of Accept-Language headers is very large.
