Is this vulnerability remotely exploitable over the internet?

Yes. An attacker can exploit it remotely by causing a victim's browser to perform a top-level GET request to an affected endpoint while the victim is authenticated to the target application.

Does an attacker need to be authenticated to exploit this issue?

The attacker does not need their own account, but the victim must be authenticated. The attack abuses the victim's existing session cookies, which the browser automatically attaches to the cross-site GET request.

What is the safest general fix pattern?

Ensure that all state-changing server functions require non-GET HTTP methods and enforce this at the framework or routing layer, combined with robust CSRF protections (such as tokens) for all mutation endpoints.
