      "value": "Network-AI is a TypeScript/Node.js multi-agent orchestrator. Prior to version 5.4.5, the MCP SSE server defaults to an empty secret (`process.env['NETWORK_AI_MCP_SECRET'] ?? ''` at `bin/mcp-server.ts:89`), which causes `_isAuthorized` (`lib/mcp-transport-sse.ts:254`) to return `true` unconditionally for every request — no `Authorization` header is required. Simultaneously, `_handleRequest` sets `Access-Control-Allow-Origin: *` (`lib/mcp-transport-sse.ts:272`) on every response, so a cross-origin browser fetch can read the result without restriction. An unauthenticated attacker who can lure a user to a malicious web page can invoke all 22 exposed MCP tools — including `config_set`, `agent_spawn`, and `blackboard_write` — against a default-configured localhost server. Version 5.4.5 patches the issue."

      "value": "Network-AI es un orquestador multiagente de TypeScript/Node.js. Antes de la versión 5.4.5, el servidor MCP SSE por defecto utiliza un secreto vacío (process.env[’NETWORK_AI_MCP_SECRET’] ?? ’’ en bin/mcp-server.ts:89), lo que provoca que _isAuthorized (lib/mcp-transport-sse.ts:254) devuelva true incondicionalmente para cada solicitud - no se requiere un encabezado Authorization. Simultáneamente, _handleRequest establece Access-Control-Allow-Origin: * (lib/mcp-transport-sse.ts:272) en cada respuesta, por lo que una recuperación de navegador de origen cruzado puede leer el resultado sin restricciones. Un atacante no autenticado que puede atraer a un usuario a una página web maliciosa puede invocar las 22 herramientas MCP expuestas - incluyendo config_set, agent_spawn y blackboard_write - contra un servidor localhost configurado por defecto. La versión 5.4.5 corrige el problema."
