CVE-2026-92938 patriksimek CVE debrief

Who should care

Defenders responsible for Node.js and vm2 deployments should assess exposure and prioritize updates. They should verify vm2 versions, review NodeVM configurations, and monitor plugin activity to ensure the security of their environments. The vulnerability's high remediation priority requires immediate attention from defenders to prevent potential attacks.

Why it matters

CVE-2026-92938 allows sandboxed plugins in vm2 to execute arbitrary native code outside the sandbox. Defenders should verify vm2 versions, review NodeVM configurations, and monitor plugin activity.

• Arbitrary native code execution outside the sandbox with host process privileges requires verification.
• Verification of vm2 versions and NodeVM configurations is necessary.
• Remediation priority is high for environments using affected vm2 versions.

Technical summary

vm2 versions 3.11.3 through 3.11.6 expose Node.js's host node:sqlite module to code running in NodeVM. Sandboxed code can create an in-memory DatabaseSync with extension loading enabled and call DatabaseSync.loadExtension() on a native library, giving the sandboxed plugin arbitrary native code execution outside the sandbox with the host process's privileges. The issue is fixed in vm2 3.11.7, and defenders should prioritize verifying vm2 versions and updating to 3.11.7 where possible. The vulnerability allows sandboxed plugins to execute arbitrary native code outside the sandbox with host process privileges, requiring verification of vm2 versions and NodeVM configurations.

Defensive priority

Defenders should prioritize verifying vm2 versions and updating to 3.11.7 where possible.

Recommended defensive actions

• Verify vm2 versions in use and update to 3.11.7 where possible.
• Review NodeVM configurations to ensure 'node:sqlite' is not permitted unnecessarily.
• Monitor for and restrict use of DatabaseSync.loadExtension() in sandboxed plugins.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
