    Package        : python-django
    Version        : 1:1.11.29-1+deb10u8
    CVE ID         : CVE-2023-31047
    Debian Bug     : 1035467

    It was discovered that there was a potential validation bypass in
    Django, a popular Python-based web development framework.

    Uploading multiple files using one form field has never been
    supported by forms.FileField or forms.ImageField, as only the last
    uploaded file was ever validated. Unfortunately, the uploading
    multiple files topic in the documentation suggested otherwise.

    In order to avoid a 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, please see:
    https://www.djangoproject.com/weblog/2023/may/03/security-releases/

    For Debian 10 buster, this problem has been fixed in version
    1:1.11.29-1+deb10u8.

    We recommend that you upgrade your python-django packages.
