Critical vm2 sandbox bug lets attackers execute code on hosts

By Bill Toulas

AI Summary

A critical sandbox escape vulnerability in vm2, the widely-used Node.js sandboxing library, allows attackers to break out of the sandbox and execute arbitrary code directly on the host system. Twelve critical vulnerabilities were disclosed in total, with vm2 used across many applications to isolate untrusted JavaScript execution. Any Node.js application relying on vm2 for security boundaries should treat this as an urgent remediation or architectural review item.
