CVE-2026-44008

Full vulnerability record from the local CVENow database.

Description

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.2, the new method neutralizeArraySpeciesBatch works with objects from the other side but can call into this side via getter on the array prototype exposing objects of the wrong side into the sandbox. This can be used to get host objects and get the host Function object. This allows attackers to write code which can escape from the VM2 sandbox and execute arbitrary commands on the host system. This vulnerability is fixed in 3.11.2.

Antes de la 3.11.2, el nuevo método neutralizeArraySpeciesBatch funciona con objetos del otro lado, pero puede llamar a este lado a través de un getter en el prototipo del array, exponiendo objetos del lado incorrecto en la sandbox. Esto puede usarse para obtener objetos del host y obtener el objeto Function del host. Esto permite a los atacantes escribir código que puede escapar de la sandbox de VM2 y ejecutar comandos arbitrarios en el sistema host. Esta vulnerabilidad está corregida en la 3.11.2."
