Echo: vm2: security update to 3.11.7

medium Tenable Cloud Security Plugin ID 472237

Description

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

 - vm2 versions from 3.9.6 before 3.11.7 fail to properly restrict access to accessor properties on frozen
 objects, allowing sandboxed scripts to bypass vm.freeze() and vm.readonly() protections. Attackers can use
 Object.getOwnPropertyDescriptor() or __lookupSetter__() to extract and invoke host object setters
 directly, mutating properties the embedder explicitly marked read-only. (CVE-2026-92949)

Solution

Update the vm2 library and its related packages to version 3.11.7 or later.
