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.
