Doc Text:
A flaw was found in vm2. This vulnerability allows an attacker executing untrusted code within the sandbox to escape isolation and achieve arbitrary code execution on the host system. When external module loading is permitted without restricting access to dependency directories, sandboxed code can load vm2 itself, create an unrestricted virtual machine environment, and run arbitrary host operating system commands.

Description OSIDB Bzimport 2026-09-17 14:02:25 UTC 
vm2 before 3.11.7 contains a remote code execution vulnerability when require.external is enabled without an explicit require.root that excludes node_modules. Sandboxed code can require vm2's own package, instantiate an unrestricted NodeVM instance, and execute arbitrary host OS commands via child_process.
