Is this vulnerability remotely exploitable?

Yes, if the `POST /webhook` endpoint is exposed to untrusted networks and authentication is disabled or not correctly enforced, an attacker can exploit it remotely by sending crafted HTTP requests.

Does an attacker need valid credentials or a token to exploit this?

No, when the webhook authentication (`auth_token` or equivalent) is unset, disabled, or not validated, the attacker does not need credentials. Network access to the endpoint is sufficient.

What is the safest general fix pattern for this issue?

Require strong, default-on authentication for the webhook endpoint and stop using client-supplied identity fields directly in authorization decisions. Instead, authenticate the caller first, then derive their effective identity and allowed chat contexts on the server side.
