CVE-2023-23969 is fixed in 3 products on 1 platform, first by python-django 1:1.11.11-1ubuntu1.19, released February 1, 2023. It is not reported as exploited. Patch Radar priority: High.
In Django 3.2 before 3.2.17, 4.0 before 4.0.9, and 4.1 before 4.1.6, theparsed values of Accept-Language headers are cached in order to avoidrepetitive parsing. This leads to a potential denial-of-service vector viaexcessive memory usage if the raw value of Accept-Language headers is verylarge.
