Impact

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.

Patches

A new version of django-sendfile2 will be released.

Workarounds

Either download django-sendfile2 0.7.0 or sanitize user input yourself, using Django's patch as a template: django/django@bd06244
