Is this vulnerability remotely exploitable?

It can be, if attackers can control a sandboxed agent or access the APIs used by sandboxed agents to submit tasks. In that case, they may be able to exploit the routing logic over the network.

What level of access does an attacker need?

An attacker must be able to act as a sandboxed agent, which typically means possessing its credentials, controlling its configuration, or exploiting another flaw to issue requests in its context.

What is the safest general fix pattern?

Centralize and harden authorization checks so that routing decisions are enforced by trusted control-plane logic. Sandboxed agents should not be able to influence which nodes they run on beyond what policy explicitly permits.
