CVE-2026-42856 PUBLISHED

Network-AI: Missing authentication on MCP HTTP endpoint allows unauthenticated privileged tool calls

Assigner: GitHub_M
Reserved: 30.04.2026 Published: 11.05.2026 Updated: 11.05.2026

Network-AI is a TypeScript/Node.js multi-agent orchestrator. Prior to 5.1.3, the MCP HTTP transport accepts JSON-RPC tools/call requests with no authentication, session, origin, or token check, and dispatches them directly to the orchestrator's tool registry. The default bind address is 0.0.0.0. As a result, any party with network reachability to the service can enumerate and invoke privileged management tools. This vulnerability is fixed in 5.1.3.
