Date Reported:
01 Feb 2022
Affected Packages:
Security database references:
In Mitre's CVE dictionary: CVE-2022-22818, CVE-2022-23833.
More information:

It was discovered that there were two vulnerabilities in Django, a popular Python-based web development framework:

  • CVE-2022-22818

    Possible XSS via {% debug %} template tag.

    The {% debug %} template tag didn't properly encode the current context, posing an XSS attack vector.

    In order to avoid this vulnerability, {% debug %} no longer outputs information when the DEBUG setting is False, and it ensures all context variables are correctly escaped when the DEBUG setting is True.

  • CVE-2022-23833

    Denial-of-service possibility in file uploads

    Passing certain inputs to multipart forms could result in an infinite loop when parsing files.

For Debian 9 Stretch, these problems have been fixed in version 1:1.10.7-2+deb9u15.

We recommend that you upgrade your python-django packages.
