Echo: vm2: security update to 3.11.4

medium Tenable Self-Hosted Container Security Plugin ID 463809

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, NodeVM exposes some process-wide
 observability builtins when they are allowed through require.builtin. The diagnostics_channel,
 async_hooks, and perf_hooks builtins are not blocked by the dangerous builtin denylist. These modules are
 process-wide, not sandbox-local. Sandboxed code can use them to observe host application data across the
 vm2 boundary. This issue has been patched in version 3.11.4. (CVE-2026-47141)

Solution

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