Echo: vm2: security update to 3.11.4

critical Tenable Cloud Security Plugin ID 458181

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, a sandbox escape vulnerability in
 vm2 allows arbitrary code execution in the host process when untrusted code is executed with async support
 on runtimes exposing WebAssembly JSPI (WebAssembly.promising / WebAssembly.Suspending). In the tested
 configuration, a JSPI-backed Promise can reach Promise.prototype.finally() in a way that bypasses the
 expected Promise-species hardening and exposes a host-originated rejection object to attacker-controlled
 species logic, breaking the sandbox boundary. This issue has been patched in version 3.11.4.
 (CVE-2026-47210)

Solution

Update the vm2 library and its related packages to version 3.11.4 or later.
