Is this vulnerability remotely exploitable over the internet?

Yes. When the File Browser instance exposes the signup page over the network and the affected configuration is in place, any remote visitor can register an account that becomes an administrator.

Does exploitation require an existing account or authentication?

No existing account is required. The flaw specifically affects the unauthenticated self-registration flow; an attacker only needs network access to the signup endpoint.

What is the safest general fix pattern for this class of bug?

Ensure that self-registered or otherwise untrusted accounts are always created with minimal, non-admin permissions, regardless of global defaults. Administrative privileges should only be assigned through explicit, authenticated workflows that require an existing administrator to grant or approve elevated roles.
