Vulnerability Snapshot
CVE-2026-92935 is rated CRITICAL — exploitation is trivial or already observed in the wild and impact is severe. Patch immediately, not on the next maintenance window.
Executive Summary
vm2 is a sandbox for running untrusted Node.js code. In versions >= 3.11.4 and <= 3.11.6, the NodeVM constructor computes hasRealRequireConfig with typeof requireOpts === 'object' && requireOpts !== null, so an array-shaped require value (for example require: []) satisfies the guard that is meant to reject nesting without an explicit require configuration. makeResolverFromLegacyOptions() then destructures the array into undefined option fields and returns a resolver containing only NESTING_OVERRIDE.vm2. As a result, an attacker who can supply JavaScript executed by a NodeVM configured with truthy nesting and an array-shaped require (e.g. new NodeVM({nesting: true, require: []})) can require the host vm2 module, create an inner NodeVM with an attacker-chosen builtin allowlist (such as child_process), and execute arbitrary commands with the privileges of the host Node.js process, escaping the sandbox. Outer builtin restrictions do not constrain the attacker-created

Frequently Asked Questions
What is CVE-2026-92935?
CVE-2026-92935 is a critical-severity vulnerability tracked under the Common Vulnerabilities and Exposures program. vm2 is a sandbox for running untrusted Node.js code. In versions >= 3.11.4 and <= 3.11.6, the NodeVM constructor computes hasRealRequireConfig with `typeof requireOpts === 'object' && requireOpts !=
Am I affected?
Affected technology is listed in the Affected Products section above. If your asset inventory contains any of them, assume in-scope until you can prove otherwise.
How urgent is the response?
Critical: do not wait for your normal patch cycle. Verify exposure today, apply the vendor patch immediately, and add detection rules for any post-exploit indicators.
How do I remediate?
Apply the vendor patch listed in the upstream advisory linked under Sources. If the patch is not yet available, follow the vendor-supplied workaround (often a config flag or feature disable) and add detections for the published exploit pattern in your SIEM. Re-scan after the patch lands to confirm the finding clears.
Where can I track exploitation activity?
Watch CISA's Known Exploited Vulnerabilities catalog for CVE-2026-92935. Cross-reference with public exploit databases and your own SIEM/IDS for indicator-of-compromise patterns. Vulnios tracks KEV status automatically and surfaces it on the asset findings view.
How does Vulnios help with this?
Vulnios continuously cross-references your asset inventory against the live CVE feed (NVD, vendor advisories, CISA KEV, and curated OSINT). When a new CVE matches your environment, you get a prioritized finding with the severity, KEV status, exploit-prediction (EPSS), and a direct path to the vendor patch. You can start a free scan from the homepage.
