      "value": "Network-AI is a TypeScript/Node.js multi-agent orchestrator. In versions 5.7.1 and earlier, the MCP SSE server allows unauthenticated cross-origin MCP tool invocation due to an empty default secret. This issue was partially addressed by CVE-2026-46701 in version 5.4.5 by closing the CORS flaw (with Access-Control-Allow-Origin now set only for localhost origins), but the empty-default-secret flaw described in the title remained: the SSE MCP server still defaulted to an empty secret, _isAuthorized() still returned true when the secret was empty, and a non-loopback bind only produced a warning. As a result, the server still ran fully unauthenticated by default. Any non-browser caller (for example, curl, SSRF, or a 0.0.0.0 bind) could invoke all 22 MCP tools (config_set, agent_spawn, blackboard_write, token_*) with no credentials. This issue was fixed in version 5.7.2."

En las versiones 5.7.1 y anteriores, el servidor SSE de MCP permite la invocación de herramientas MCP de origen cruzado no autenticada debido a un secreto predeterminado vacío. Este problema fue abordado parcialmente por CVE-2026-46701 en la versión 5.4.5 al cerrar la falla de CORS (con Access-Control-Allow-Origin ahora configurado solo para orígenes de localhost), pero la falla del secreto predeterminado vacío descrita en el título permaneció: el servidor SSE de MCP todavía usaba un secreto vacío por defecto, _isAuthorized() todavía devolvía verdadero cuando el secreto estaba vacío, y un enlace no-loopback solo producía una advertencia. Como resultado, el servidor todavía se ejecutaba completamente sin autenticación por defecto. Cualquier llamador que no sea un navegador (por ejemplo, curl, SSRF, o un enlace 0.0.0.0) podía invocar las 22 herramientas MCP (config_set, agent_spawn, blackboard_write, token_*) sin credenciales. Este problema fue solucionado en la versión 5.7.2."
