Overview
network-ai is an AI agent orchestration framework for TypeScript/Node.js - 29 adapters (LangChain, AutoGen, CrewAI, OpenAI Assistants, LlamaIndex, Semantic Kernel, Haystack, DSPy, Agno, MCP, OpenClaw, A2A, Codex, MiniMax, NemoClaw, APS, Copilot, LangGraph, Anthropic Compu
Affected versions of this package are vulnerable to Origin Validation Error due to the default configuration setting an empty secret in the process.env['NETWORK_AI_MCP_SECRET'] environment variable, which causes the authorization check in the function to always return true. Combined with the unconditional application of the Access-Control-Allow-Origin: * header in the function, this allows unauthenticated cross-origin requests to invoke sensitive MCP tools. An attacker can modify orchestrator configuration, spawn arbitrary agents, corrupt shared agent state, or tamper with token management by luring a user to visit a malicious web page while the server is running locally.
