Hi,
The following vulnerability was published for python-django:
CVE-2023-31047: Potential bypass of validation when uploading
multiple files using one form field
Uploading multiple files using one form field has never been
supported by forms.FileField or forms.ImageField as only the last
uploaded file was validated. Unfortunately, Uploading multiple files
topic suggested otherwise.
In order to avoid the vulnerability, ClearableFileInput and
FileInput` form widgets now raise ValueError when the multiple HTML
attribute is set on them. To prevent the exception and keep the old
behavior, set allow_multiple_selected to True.
For more details on using the new attribute and handling of multiple
files through a single field, see Uploading multiple files.
