- CWE-770
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.
Affected configurations
• djangoproject django (>= 3.2 < 3.2.17)
• djangoproject django (>= 4.0 < 4.0.9)
• djangoproject django (>= 4.1 < 4.1.6)
• debian debian linux 10.0
