How broadly exploitable is this vulnerability?

The vulnerability is broadly exploitable wherever the JSON-RPC endpoint is reachable over the network. Because the unsafe evaluation happens before authorization, an attacker does not need valid credentials, only network access to the COSMOS instance.

Does an attacker need authenticated access or a COSMOS account?

No. The flaw is in the pre-authorization handling of JSON-RPC requests. An unauthenticated attacker can send specially crafted requests to trigger `eval` on their supplied parameter strings.

What is the safest general fix pattern for this class of bug?

The most robust fix pattern is to eliminate all uses of `eval` (and similar dynamic code execution primitives) on user-supplied data, replace them with strict data parsing, and restructure request handlers so that authentication and authorization checks run before any processing that could execute logic derived from the request.
