The number of files parts parsed is now limited via a new DATA_UPLOAD_MAX_NUMBER_FILES setting.

CVE-2023-24580

An issue was discovered in the Multipart Request Parser in Django 3.2 before 3.2.18, 4.0 before 4.0.10, and 4.1 before 4.1.7. Passing certain inputs (e.g., an excessive number of parts) to multipart forms could result in too many open files or memory exhaustion, and provided a potential vector for a denial-of-service attack.

For Debian 10 Buster, this problem has been fixed in version 1:1.11.29-1+deb10u7.

We recommend that you upgrade your python-django packages.
