Overview

CVE-2026-47140 is a critical-severity vulnerability. It was published on June 12, 2026 and has a CVSS 3.1 base score of 10.0 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 10.0, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
