CVE-2026-42856 Details
Description
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.
A vulnerability exists in Network-AI versions prior to 5.1.3, where the MCP HTTP transport accepts JSON-RPC tools/call requests without any form of authentication, session, origin, or token verification. These requests are sent directly to the orchestrator's tool registry. The service is exposed on all network interfaces by default, allowing any party with network access to the service to enumerate and invoke privileged management tools. This includes capabilities such as reading and modifying the live orchestrator configuration, managing registered agents, creating or revoking security tokens, and adjusting global budget ceilings.
Users are advised to update to Network-AI version 5.1.3 or later. Additionally, it is recommended to configure the server to bind only to the loopback interface by default, and to implement authentication checks for the MCP HTTP endpoint before processing tools/call requests.
