How broadly exploitable is this vulnerability?

Exploitability depends on network reachability. If MCPJam Inspector is bound to 0.0.0.0 on a machine reachable from untrusted networks, any remote attacker who can reach the port can potentially exploit the vulnerability via a crafted HTTP request.

Does an attacker need valid credentials or local access?

No. The issue arises because critical functionality is exposed without authentication. Network access to the listening port is sufficient; no local access or credentials are inherently required.

What is the safest general fix pattern for developers of similar tools?

Enforce authentication and authorization for all operations that can install, configure, or execute code, and adopt secure-by-default network bindings (localhost-only). Treat developer and "inspector" APIs as high-risk surfaces that must be gated, even in local-first tools.
