Prior to 3.1.3, executeJavaScriptCode() accepted caller-provided nodeVMOptions and merged them over the default NodeVM security settings in packages/components/src/utils.ts. An authenticated attacker reaching packages/server/src/routes/node-custom-functions/index.ts could run a custom function that imported flowise-components/dist/src/utils.js, called executeJavaScriptCode() again with nodeVMOptions.require.builtin set to allow all built-in modules, and then required child_process to execute arbitrary system commands as root on the Flowise server. This issue is fixed in version 3.1.3."},{"lang":"es","value":"Flowise es una interfaz de usuario de arrastrar y soltar para construir un flujo de modelo de lenguaje grande personalizado. Antes de la versión 3.1.3, executeJavaScriptCode() aceptaba nodeVMOptions proporcionadas por el llamador y las fusionaba sobre la configuración de seguridad predeterminada de NodeVM en packages/components/src/utils.ts. Un atacante autenticado que llegara a packages/server/src/routes/node-custom-functions/index.ts podría ejecutar una función personalizada que importara flowise-components/dist/src/utils.js, llamara a executeJavaScriptCode() de nuevo con nodeVMOptions.require.builtin configurado para permitir todos los módulos incorporados, y luego requiriera child_process para ejecutar comandos de sistema arbitrarios como root en el servidor de Flowise.
