HIGH
Django contains Uncontrolled Resource Consumption via cached header
Published February 1, 2023Updated September 20, 2024Source: osv
Details
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.
Remediation
Upgrade to the fixed version using your package manager.
pip
Update django to 4.0.9 or laterpip install "django>=4.0.9"
pip
Update django to 3.2.17 or laterpip install "django>=3.2.17"
pip
Update django to 4.1.6 or laterpip install "django>=4.1.6"
After upgrading, run your dependency scanner again to confirm the vulnerability is resolved.
