  - 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. (CVE-2023-31047)

  - In Django 3.2 before 3.2.20, 4 before 4.1.10, and 4.2 before 4.2.3, EmailValidator and URLValidator are
    subject to a potential ReDoS (regular expression denial of service) attack via a very large number of
    domain name labels of emails and URLs. (CVE-2023-36053)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
