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.
