How exploitable is this vulnerability in practice?

The vulnerability is highly exploitable in environments using the Login V2 UI, as it can be triggered by any user interacting with the public login page where misaligned UI and backend policy enforcement exist.

Does an attacker need existing access to exploit this issue?

No prior account or special privileges are required. An unauthenticated user can attempt to register or sign in with password through the affected login UI flows.

What is the safest general fix pattern for this type of issue?

Make organization policies the single source of truth enforced at the backend for every authentication and registration action, and treat front-end controls as non-authoritative hints rather than security gates.
