CVE-2026-47140 · vm2: NodeVM builtin denylist bypass via process and inspector/promises allows host code execution

This page contains facts from public vulnerability sources. Check the original advisory before updating.

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, NodeVM blocks several dangerous Node.js builtins such as module, worker_threads, cluster, vm, repl, and inspector. However, the denylist misses process and inspector/promises. Both can be used from sandboxed code to reach host-side execution primitives. This allows sandboxed code to bypass the intended builtin restrictions and execute code in the host process. This issue has been patched in version 3.11.4.
