AI-suggested
A fix is available in vm2 version 3.11.2. Users should upgrade to vm2 3.11.2 or later to remediate this vulnerability. No alternative mitigations are specified by the vendor advisory. Since this is a code execution vulnerability due to sandbox escape, upgrading is the recommended and effective remediation.
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.
