CVE-2026-47686
CriticalCVSS 9.9Summary
vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.6, handleException() in lib/setup-sandbox.js sanitizes SuppressedError.error, SuppressedError.suppressed, and AggregateError.errors but does not sanitize Error.cause, allowing sandbox code to obtain a powerful host object such as process from an embedder-exposed host function that throws an error with that object as its cause and then execute arbitrary host commands. This issue is fixed in version 3.11.6.
Risk Assessment
Allows sandbox escape and arbitrary code execution on the host, potentially leading to full system compromise.
Recommendation
Upgrade vm2 to version 3.11.6 or later.
