Is this vulnerability remotely exploitable over the internet?

Yes. If the AVideo instance exposes the Live plugin endpoints (on_publish_done.php and stats.json.php) publicly and they are left unauthenticated, an attacker with basic network access can exploit the issue without logging in.

Does an attacker need a valid user account or broadcaster access?

No. The described behavior allows unauthenticated users to enumerate active stream keys and then send crafted POST requests to terminate streams. No user account or broadcaster role is required under the vulnerable configuration.

What is the safest general fix pattern?

The most robust approach is to enforce authentication and authorization on all critical stream-control endpoints. This typically involves requiring a strong shared secret or signed token between the RTMP server and the AVideo application, verifying that callbacks are from trusted sources, and ensuring that only authorized principals can terminate specific streams.
