Impact

S3FileMiddleware is vulnerable to relative path traversal attacks, where an attacker can use a modified request to escape pre-signed upload locations and have the Django application load files from random locations into request.FILES

Depending on how files are handled, this may lead to confidentiality and integrity issues.

Patches

Django-S3File urges all users to update to a patched version >=7.0.2.
