PraisonAI before 4.6.78 exposes the MCP HTTP-stream transport without authentication by default: the CLI –api-key option defaults to None, and the server only enforces Authorization\/Bearer checks when an API key is configured. When an operator runs ‘praisonai mcp serve –transport http-stream’ without an API key, an unauthenticated client (no Authorization header, and no Origin header, which is also permitted) can initialize a session, enumerate the available tools (tools\/list), and invoke tools (tools\/call). Additionally, the dispatcher forwards tool-call arguments to handlers without validating them against the advertised inputSchema. The server binds to 127.0.0.1 by default, so remote exploitation requires the operator to bind to a network-accessible address (e.g., –host 0.0.0.0).<\/p>\n","protected":false},"excerpt":{"rendered":"
