Is this vulnerability remotely exploitable over the network?

Yes. If the FUXA interface is reachable over the network and the Node-RED plugin is enabled on an affected version, an unauthenticated remote attacker can exploit the issue without prior access.

Does an attacker need valid credentials or a user account to exploit this?

No. The weakness is an authentication bypass affecting critical Node-RED functionality, so exploitation does not require a valid username or password when the vulnerable configuration is present.

What is the safest general fix pattern for this kind of issue?

The most robust fix pattern is to ensure that all critical plugin operations are guarded by centralized, mandatory authentication and authorization checks. Every route that exposes scripting, configuration, or administrative control should use the same hardened access-control mechanisms as the core application, with no unauthenticated exceptions.
