CVE-2026-43999

Descripción

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.
