Descriptions

In Django 3.2 before 3.2.19, 4.x before 4.1.9, and 4.2 before 4.2.1, it was possible to bypass validation when using one form field to upload multiple files. This multiple upload has never been supported by forms.FileField or forms.ImageField (only the last uploaded file was validated). However, Django's "Uploading multiple files" documentation suggested otherwise.

A bypass of validation flaw was found in python-django. When uploading multiple files using one form field, an attacker could upload multiple files without validation due to the server only validating the last file uploaded.
