Is this vulnerability remotely exploitable?

Yes. If the live stream control endpoint is reachable over the network, an attacker can exploit this issue remotely by supplying a malicious `streamerURL` pointing to their own verification server.

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

The attacker only needs network access to the vulnerable endpoint; prior authentication is not required, because the vulnerability itself bypasses the intended authentication mechanism.

What is the safest general fix pattern?

Remove client influence over authentication infrastructure: ensure that all token verification calls use fixed, server-controlled URLs, enforce strict host validation, and apply robust server-side authorization before executing any live stream control operations.
