Vulnerability changelog

===========================

*May 3, 2023*

Django 3.2.19 fixes a security issue with severity "low" in 3.2.18.

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
:class:`.forms.FileField` or :class:`.forms.ImageField` as only the last
uploaded file was validated. Unfortunately, :ref:`uploading_multiple_files`
topic suggested otherwise.

In order to avoid the vulnerability, :class:`~django.forms.ClearableFileInput`
and :class:`~django.forms.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 :ref:`uploading_multiple_files`.
