CVE-2023-23969
HIGHDjango 3.2-3.2.16 4.0-4.0.8 4.1-4.1.5 - Denial of Service via Accept-Language Header Parsing
Title source: llmDescription
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.
