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.","state":0,"publishedAt":"2026-06-12T15:16:28.137+00:00","modifiedAt":"2026-10-26T11:10:00.157+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","score":10,"severity":"CRITICAL"}],"references":["https://github.com/advisories/GHSA-g644-9gfx-q4q4","https://github.com/patriksimek/vm2/commit/01a7552add345d5a6862623884e6b79a85bf0568","https://github.com/patriksimek/vm2/commit/86ab819f202c3a8dad88cef5705f2e416c5188d7","https://github.com/patriksimek/vm2/releases/tag/v3.11.4","https://github.com/patriksimek/vm2/security/advisories/GHSA-m4wx-m65x-ghrr"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-47137","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-913"],"productCriteria":[],"sourceDates":{"published":"2026-06-12T15:16:28.137","lastModified":"2026-10-26T11:10:00.157"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
