Django 4.0.9 release notes
==========================
*February 1, 2023*
Django 4.0.9 fixes a security issue with severity "moderate" in 4.0.8.
CVE-2023-23969: Potential denial-of-service via ``Accept-Language`` headers
===========================================================================
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 large header values are sent.
In order to avoid this vulnerability, the ``Accept-Language`` header is now
parsed up to a maximum length.
