CVE-2023-23969
HIGH7.5EPSS 6.1%python-django - security update
Published: 2/1/2023Modified: 4/28/2026
Description
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.
