Echo: vm2: security update to 3.11.6

critical Tenable Self-Hosted Container Security Plugin ID 465367

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 3.11.6, handleException() in lib/setup-sandbox.js
 sanitizes SuppressedError.error, SuppressedError.suppressed, and AggregateError.errors but does not
 sanitize Error.cause, allowing sandbox code to obtain a powerful host object such as process from an
 embedder-exposed host function that throws an error with that object as its cause and then execute
 arbitrary host commands. This issue is fixed in version 3.11.6. (CVE-2026-47686)

Solution

Update the vm2 library and its related packages to version 3.11.6 or later.
