CVE-2026-47210 vm2 sandbox escape via JSPI-backed Promise `.finally()` species bypass

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, a sandbox escape vulnerability in vm2 allows arbitrary code execution in the host process when untrusted code is executed with async support on runtimes exposing WebAssembly JSPI WebAssembly.promising / WebAssembly.Suspending...

CVE-2026-47208

Summary: CVE-2026-47208 affects vm2 prior to 3.11.4, enabling sandbox breakout and potential remote code execution. The root cause is in vm2’s sandbox implementation, where the localPromise constructor manipulates Promise.species and, via a crafted Promise subclass, can trigger a host-realm error...

CVE-2026-47208 vm2: Sandbox Breakout Using Promise Species

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, VM2 suffers from a sandbox breakout vulnerability. This allows attackers to write code which can escape from the VM2 sandbox and execute arbitrary commands on the host system. This issue has been patched in version 3.11.4...

CVE-2026-47137

Summary (CVE-2026-47137): The vm2 sandbox (NodeVM) had a bypass in versions prior to 3.11.4 where nesting: true with an unspecified require allowed full host RCE. The issue arose because a security check (options.nesting === true && options.require === false) only catches explicit require: false;...
