CVE-2026-47141

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, NodeVM exposes some process-wide observability builtins when they are allowed through require.builtin. The diagnostics_channel, async_hooks, and perf_hooks builtins are not blocked by the dangerous builtin denylist. These modules are process-wide, not sandbox-local. Sandboxed code can use them to observe host application data across the vm2 boundary. This issue has been patched in version 3.11.4.

Summary		(es) vm2 es una vm/sandbox de código abierto para Node.js. Antes de la versión 3.11.4, NodeVM expone algunos integrados de observabilidad a nivel de proceso cuando se permiten a través de require.builtin. Los integrados diagnostics_channel, async_hooks y perf_hooks no son bloqueados por la lista de denegación de integrados peligrosos. Estos módulos son a nivel de proceso, no locales a la sandbox. El código en sandbox puede usarlos para observar datos de la aplicación anfitriona a través del límite de vm2. Este problema ha sido parcheado en la versión 3.11.4.
