django-s3file is vulnerable to relative path traversal

Details

### 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.
