Is this vulnerability remotely exploitable?

Yes. It is exploitable over the web interface, but only by users who can access the assignment configuration upload functionality (typically instructors or equivalent privileged roles).

What level of access does an attacker need to exploit this?

The attacker must be able to authenticate and successfully upload a ZIP file to the `upload_config_files` endpoint. Exploitation is not generally possible by unauthenticated users or students without that permission.

What is the safest general fix pattern?

The most robust fix is to canonicalize every path derived from ZIP entry names and verify that it stays within a predefined base directory before writing any files. Entries that resolve outside this directory or contain traversal sequences should be rejected.
