Echo: vm2: security update to 3.11.7

critical Tenable Self-Hosted Container Security Plugin ID 472227

Description

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

 - vm2 versions 3.10.2 through 3.11.6 contain a sandbox escape vulnerability on Node.js 26 where
 Promise.prototype.finally() bypasses vm2's wrapper protections due to a stale PromiseThenLookupChain
 protector in V8 14.6. Attackers can exploit this by creating an async function that returns a Promise with
 an attacker-controlled constructor Symbol.species, allowing them to reach the host Function constructor
 and process object for arbitrary code execution. (CVE-2026-92944)

Solution

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