Is this vulnerability remotely exploitable?

Yes. As long as the Gogs instance is reachable over the network and `RequireSigninView` is disabled, any remote user can send upload requests to the affected endpoints without logging in.

Does an attacker need an account or any special privileges to exploit this?

No user account or special privileges are required in the vulnerable configuration. Network access to the Gogs web interface is sufficient to upload arbitrary files.

What is the safest general fix pattern?

The safest pattern is to enforce explicit authorization checks on all file upload endpoints so that only authenticated and properly authorized users can upload. Complement this with secure-by-default settings that do not expose write actions to unauthenticated users and with quotas and limits on uploads.
