Is this vulnerability remotely exploitable?

Yes. Because account registration is public, a remote attacker can create an account and then exploit the authorization bypass over the network using the exposed tenant management APIs.

Does an attacker need elevated privileges or admin access?

No. The issue arises precisely because any authenticated user, even one with a newly created low-privilege account, can operate on arbitrary tenant IDs.

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

Enforce strict per-tenant authorization on all tenant management endpoints, binding operations to the caller's tenant context on the server side and requiring appropriate roles (e.g., tenant admin) for sensitive actions such as updates and deletions.
