Is this vulnerability remotely exploitable?

Yes. Any remote client that can reach the `/sessions/:sessionKey/kill` endpoint and present a valid bearer token may be able to exploit it, depending on network exposure and token distribution.

Does exploitation require admin credentials?

No. The issue stems from missing scope and ownership validation, so a non-admin bearer token may be sufficient to terminate sessions belonging to other users or contexts.

What is the safest general fix pattern?

Introduce strict authorization checks on the kill route, ensuring that only appropriately scoped admin or operator roles can terminate arbitrary sessions, and that non-admin users are limited to their own sessions. Centralizing these checks in an authorization layer helps avoid future inconsistencies.
