Security Report

4.2

Use Caution4.2High Risk

Switchboard is a well-designed inter-agent message bus with clear architecture and reasonable security defaults. Authentication is required for all operations (bearer token), and permissions are appropriately scoped to its purpose. However, three moderate issues warrant attention: (1) the shared-token model creates identity ambiguity and allows token holders to impersonate any agent, (2) SSRF protection relies on operator configuration with no safe default, and (3) the daemon's prompt-injection surface requires careful allowlisting that users may misconfigure. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity).
