CVE-2026-47698

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 reach e.constructor.constructor for arbitrary host command execution. This issue is fixed in version 3.11.6.

Summary		(es) vm2 es una vm/sandbox de código abierto para Node.js. Antes de la versión 3.11.6, lib/bridge.js y lib/setup-sandbox.js no logran bloquear la indirección apilada a través de Function.prototype.call alrededor de mutadores peligrosos de getter y setter del prototipo del host, permitiendo que el código de la sandbox rompa la cadena de prototipos de un intrínseco del host y alcance e.constructor.constructor para la ejecución arbitraria de comandos del host. Este problema se ha corregido en la versión 3.11.6.
