# Django 5.2 documentation

# Django 4.1.7 release notes

February 14, 2023

Django 4.1.7 fixes a security issue with severity “moderate” and a bug in 4.1.6.

## CVE-2023-24580: Potential denial-of-service vulnerability in file uploads

Passing certain inputs to multipart forms could result in too many open files or memory exhaustion, and provided a potential vector for a denial-of-service attack.

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

## Bugfixes

- Fixed a bug in Django 4.1 that caused a crash of model validation on `ValidationError` with no `code` (#34319).
