CVE-2023-23969 (GCVE-0-2023-23969)

Vulnerability from cvelistv5 – Published: 2023-02-01 00:00 – Updated: 2025-03-27 14:17

Summary

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.

Severity

7.5 (High)
