Is this vulnerability remotely exploitable?

Yes. If the Bagisto instance is reachable over the network and the `/install/api/*` routes are accessible, an attacker can exploit the vulnerability remotely without prior access.

Does an attacker need any credentials or an existing account?

No credentials are required. The affected installer API endpoints do not enforce authentication, so any unauthenticated user with network access can send requests to them.

What is the safest general fix pattern?

The safest pattern is to completely disable or remove installer routes and logic once installation is finished, and ensure any remaining setup-related functionality is protected by strong authentication and authorization checks tied to the application's runtime state.
