Is this vulnerability remotely exploitable?

Yes. The description indicates that the attack can be carried out remotely against systems where the localGPT backend server is reachable over the network.

What level of access does an attacker need?

An attacker typically needs only network access to the vulnerable backend server. In the absence of strong authentication or authorization on the upload endpoint, even unauthenticated users may be able to exploit it.

What is the safest general fix pattern?

Constrain the upload functionality by enforcing strict authentication and authorization, validating file types and sizes, and ensuring that uploaded files are stored in non-executable, isolated locations. Combine this with a clear policy on which users and workflows are allowed to upload which kinds of content.
