Is this vulnerability remotely exploitable?

Yes. The `/api/upload` endpoint is exploitable remotely, and because it lacks authentication, an attacker does not need valid credentials to upload arbitrary files.

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

Only network access to the affected FUXA instance is required. If the service is reachable over HTTP/HTTPS from the attacker's location, the vulnerability can be exploited without prior access or an existing account.

What is the safest general fix pattern for this issue?

Protect file upload endpoints with strict authentication and authorization, validate and constrain uploaded file types, and ensure that uploaded data is stored in non-executable, segregated locations where it cannot overwrite critical system or authentication files.
