CVE-2026-44005 is a critical sandbox escape vulnerability in vm2, the Node.js sandbox library. Affected versions 3.9.6 through 3.10.5 expose mutable bridge proxies for real host-realm intrinsic prototypes. When attacker-controlled JavaScript executes inside a default VM or an inherited NodeVM, writes performed through the bridge are forwarded into the underlying host objects via bridge logic including otherReflectSet() and otherReflectDefineProperty(). This allows sandboxed code to mutate shared host prototypes such as Object.prototype, Array.prototype, and Function.prototype from inside the sandbox, breaking the intended isolation boundary between sandbox and host.
