Doc Text:
A flaw was found in vm2. The sandbox environment fails to restrict access to the child_process module, which handles system command execution. In environments configured to allow built-in modules, an attacker capable of running untrusted code within the sandbox can load this module to break containment. This can result in arbitrary code execution on the underlying host system.

Description OSIDB Bzimport 2026-09-22 18:38:34 UTC
vm2 NodeVM versions before 3.12.1 contain a sandbox escape vulnerability where the DANGEROUS_BUILTINS denylist omits child_process despite blocking other host-spawning modules. Attackers can require child_process and execute arbitrary commands on the host system when NodeVM is configured with builtin:['*'] or explicit child_process allowance.
