CVE-2026-47698 is a sandbox-escape vulnerability in vm2, an open-source sandbox for Node.js, affecting versions before 3.11.6. The bridge and sandbox setup components fail to block stacked indirection through Function.prototype.call around dangerous host prototype getter and setter mutators. Sandboxed code can sever a host intrinsic's prototype chain and access e.constructor.constructor, enabling arbitrary command execution on the host.
