Echo: vm2: security update to 3.11.7

critical Tenable Self-Hosted Container Security Plugin ID 472220

Description

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

- vm2 is a sandbox for running untrusted Node.js code. In versions >= 3.11.4 and <= 3.11.6, the NodeVM
constructor computes `hasRealRequireConfig` with `typeof requireOpts === 'object' && requireOpts !==
null`, so an array-shaped `require` value (for example `require: []`) satisfies the guard that is meant to
reject nesting without an explicit require configuration. `makeResolverFromLegacyOptions()` then
destructures the array into undefined option fields and returns a resolver containing only
`NESTING_OVERRIDE.vm2`. As a result, an attacker who can supply JavaScript executed by a NodeVM configured
with truthy `nesting` and an array-shaped `require` (e.g. `new NodeVM({nesting: true, require: []})`) can
require the host `vm2` module, create an inner NodeVM with an attacker-chosen builtin allowlist (such as
`child_process`), and execute arbitrary commands with the privileges of the host Node.js process, escaping
the sandbox. Outer builtin restrictions do not constrain the attacker-created inner NodeVM. This issue is
fixed in vm2 3.11.7. (CVE-2026-92935)

Solution

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