Is this vulnerability remotely exploitable?

Yes, it is remotely exploitable over the web interface, but the attacker must first have valid credentials to authenticate to the Brave CMS instance.

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

Any authenticated user account is sufficient. Once logged in, the attacker can send crafted requests to the role update endpoint to modify roles, including promoting themselves to Super Admin.

What is the safest general fix pattern?

The safest approach is to enforce explicit authorization for all role and permission management operations by attaching appropriate permission-checking middleware or policies to the affected route and verifying that only designated administrative roles can change user roles.
