Is this vulnerability remotely exploitable?

Yes. Any remote client capable of presenting a JWT to the application may attempt to exploit this flaw by manipulating the `role` or `scope` claims, subject to how tokens are generated and verified.

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

Typically, the attacker needs the ability to obtain or create JWTs recognized by the application. If token signing is weak or misconfigured, they may be able to forge tokens; otherwise, even a low-privileged authenticated user may exploit the issue by modifying claims in their existing token if signature checks are absent or bypassed.

What is the safest general fix pattern?

The most robust fix is to centralize authorization on the server side: use the user's identity from the JWT to look up roles and permissions in a trusted store and base all access decisions on that server-side data, ignoring or strictly constraining privilege-related claims from the token.
