Is this vulnerability remotely exploitable?

Yes. Because the export_file endpoint is unauthenticated and CORS is overly permissive, a remote attacker can exploit this from a browser or any client that can reach the Vociferous API, without needing local access or UI interaction.

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

The attacker must be able to send HTTP requests to the Vociferous backend. In typical setups where the backend listens on localhost or a user's machine, a malicious website can trigger cross-origin requests from the victim's browser if CORS allows it. No application login or credentials are required.

What is the safest general fix pattern?

Constrain file writes to a specific, server-defined directory; normalize and validate all filenames; reject any paths that escape the allowed directory; and require authentication for file-writing operations. Additionally, tighten CORS to only allow trusted origins that are under the developer's control.
