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...

CVE-2026-47698 vm2: Sandbox Breakout Using Dangerous Host Proto Mutators

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.6, lib/bridge.js and lib/setup-sandbox.js fail to block stacked indirection through Function.prototype.call around dangerous host prototype getter and setter mutators, allowing sandbox code to sever a host intrinsic's prototype chain and...
