Is this vulnerability remotely exploitable?

Yes. If the Coral Server SSE endpoint is exposed over the network, an attacker who can reach `/sse/v1/...` may attempt to attach to or interfere with existing sessions, depending on how identifiers and tokens are managed.

What level of access does an attacker need?

The attacker generally needs network access to the Coral Server API and the ability to craft SSE connection requests. If session identifiers or tokens are predictable, leaked, or otherwise obtainable, the attacker may not need to be a legitimate participant in the target session.

What is the safest general fix pattern?

Apply strict authorization checks to the SSE endpoint so that establishing a connection for a given session requires: (1) authenticated identity, and (2) server-side verification that this identity is an authorized participant of that specific session, using centralized access control logic.
