DescriptionNVD

vm2 is an open source vm/sandbox for Node.js. In version 3.10.4, vm2 is vulnerable to full sandbox escape with arbitrary code execution. Attacker code inside VM.run() obtains host process object and runs host commands with zero host cooperation. This issue has been patched in version 3.10.5.

AnalysisAI

Full sandbox escape with arbitrary code execution allows remote attackers to break out of vm2's Node.js sandbox environment (version 3.10.4) and execute commands on the host system. Attacker-controlled code running inside VM.run() can obtain the host process object and execute arbitrary host commands without any cooperation from the host application. …

RemediationAI

Within 24 hours: Identify all systems running vm2 versions ≤3.10.4 using dependency scanning (npm audit, SBOM tools). Within 7 days: Upgrade all instances to vm2 version 3.10.5 or later and validate in staging environment. …
