# Django 3.2.17 release notes

*February 1, 2023*

Django 3.2.17 fixes a security issue with severity "moderate" in 3.2.16.

## 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.
