Official Description

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, the fix for GHSA-8hg8-63c5-gwmx (CVE-2023-37903) introduced a check in nodevm.js line 263 that blocks the combination nesting: true + require: false. However, the check uses strict equality (options.require === false), which is trivially bypassed by omitting the require option entirely. When require is not specified, options.require is undefined, not false. The strict equality check fails, so the security guard is skipped. Immediately after (line 280), the destructuring default require: requireOpts = false assigns requireOpts = false, producing the exact configuration the patch was designed to prevent. This issue has been patched in version 3.11.4.

Risk Analysis

This critical vulnerability in vm2, a Node.js sandbox, allows attackers to bypass a security guard intended to prevent sandbox escapes. A strict equality check in the previous fix was trivially bypassed by omitting the 'require' option, leading to the intended secure configuration being skipped. With a CVSS score of 10.0, this issue is extremely severe and allows for complete system compromise.

No public exploit is currently known for this vulnerability. The flaw is remotely exploitable due to its network attack vector and low attack complexity.

Recommended Action

Upgrade vm2 to version 3.11.4 or later. Ensure that all Node.js applications using vm2 are updated to the patched version.

Technical Analysis

CVE-2026-47137 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 10.0.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
