A flaw was found in vm2 (before 3.11.1). With nesting: true, sandbox code can require('vm2') regardless of outer require settings (including require: false), spawn an inner NodeVM with unrestricted require, and execute arbitrary OS commands on the host. Fixed in 3.11.1. vm2: vm2: Arbitrary code execution via nested NodeVM bypass vm2 NodeVM is vulnerable to sandbox escape when nesting is enabled, allowing unconditional require of vm2 and creation of an unrestricted inner NodeVM. An attacker with low privileges who can run code in a nested NodeVM may execute arbitrary OS commands on the host. Fixed in vm2 3.11.1.
