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.
