CVE-2026-47137 vm2: GHSA-8hg8-63c5-gwmx patch bypass: nesting:true without explicit require still allows full RCE

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...

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;...

Summary 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...

CVE-2026-44007 vm2: nesting: true bypasses require: false, allowing sandbox escape to arbitrary OS command execution

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.1, when a NodeVM is created with nesting: true, sandbox code can unconditionally require'vm2' regardless of the outer VM's require configuration — including require: false. With access to vm2, the sandbox constructs a new inner NodeVM wi...

CVE-2026-44007

vm2 contains a vulnerability where creating a NodeVM with nesting: true allows sandbox code to bypass outer VM restrictions (e.g., require: false) and construct an inner NodeVM with unrestricted require settings to execute host commands. Affected: vm2 versions up to 3.11.0 (and prior to 3.11.1). ...
