# django-sendfile2 before 0.7.0 contains reflected file download vulnerability

django-sendfile2 up to 0.6.1 does not protect against reflected file downloads, so a file name taken from user input can be served with an attacker-chosen name. An attacker can craft a link that makes a victim's browser download a file the server returns under a name the attacker controls.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- pypi:django-sendfile2 affected < 0.7.0 fixed 0.7.0

## How to check

- Run `pip show django-sendfile2` and confirm the installed version is below `0.7.0`.
- Search the codebase for calls to django-sendfile2 and check whether the file name passed to it comes from request parameters or other user input.

## Fix

- Upgrade django-sendfile2 to `0.7.0`.
- If upgrading is not possible, sanitize user-supplied file names before passing them to django-sendfile2, following Django's patch for CVE-2022-36359 (https://github.com/django/django/commit/bd062445cffd3f6cc6dcd20d13e2abed818fa173).

## From the sources

Similar to CVE-2022-36359 for Django, django-sendfile2 did not protect against a reflected file download attack in version 0.6.1 and earlier. If the file name used by django-sendfile2 was derived from user input, then it would be possible to perform a such an attack. A new version of django-sendfile2 will be released. Either download django-sendfile2 0.7.0 as a workaround or sanitize user input yourself, using Django's patch as a template: https://github.com/django/django/commit/bd062445cffd3f6cc6dcd20d13e2abed818fa173
