In 3.10.5, NodeVM's require.root path restriction can be bypassed using filesystem symlinks, allowing sandboxed code to load modules from outside the allowed root directory in host context. Because path validation uses path.resolve() (which does not dereference symlinks) but module loading uses Node's native require() (which does), an attacker can load arbitrary host-realm modules and achieve remote code execution. This vulnerability is fixed in 3.11.0."},{"lang":"es","value":"vm2 es una máquina virtual/sandbox de código abierto para Node.js. En 3.10.5, la restricción de ruta require.root de NodeVM puede ser eludida usando enlaces simbólicos del sistema de archivos, permitiendo que el código en el sandbox cargue módulos desde fuera del directorio raíz permitido en el contexto del host. Debido a que la validación de rutas usa path.resolve() (que no desreferencia enlaces simbólicos) pero la carga de módulos usa el require() nativo de Node (que sí lo hace), un atacante puede cargar módulos arbitrarios del ámbito del host y lograr ejecución remota de código.
