Description (CNA)
vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, NodeVM's builtin allowlist can be bypassed when the module builtin is allowed (including via the '*' wildcard). The module builtin exposes Node's Module._load(), which loads any module by name directly in the host context, completely bypassing vm2's builtin restriction. This allows sandboxed code to load excluded builtins like child_process and achieve remote code execution. This vulnerability is fixed in 3.11.0.

A flaw was found in vm2 (before 3.11.0). When the module builtin is allowed (including via wildcard), sandboxed code can call Module._load() in the host context, bypassing the builtin allowlist and loading excluded modules such as child_process for remote code execution. Fixed in 3.11.0.
