Is this vulnerability remotely exploitable over the network?

Yes. The description indicates that an unauthenticated, remote attacker can trigger the path traversal, so any network-accessible FUXA instance up to version 1.2.9 may be exposed.

Does an attacker need valid credentials to exploit this?

No. This specific issue is described as unauthenticated, meaning that exploitation does not require prior login or user account access, as long as the attacker can reach the vulnerable endpoints.

What is the safest general fix pattern for developers?

Implement strict path canonicalization and base-directory enforcement for all file operations, reject traversal sequences outright, and ensure that any endpoint capable of writing files is gated by robust authentication and authorization. Combine this with least-privilege filesystem permissions to minimize damage if a flaw is missed.
