CVE-2026-47698

In vm2 versions ≤3.11.5, sandbox code exploits stacked indirection via Function.prototype.call to bypass prototype-chain protections in lib/bridge.js and lib/setup-sandbox.js, severing host intrinsic chains and reaching e.constructor.constructor for arbitrary host command execution. A published P...
