CVE-2026-44007
Description
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.
Statement
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.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
