Echo: vm2: security update to 3.11.7

high Tenable Cloud Security Plugin ID 472232

Description

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

 - vm2 through 3.11.6 contains a builtin-module denylist bypass in NodeVM. When the embedder uses the builtin
 wildcard together with negative entries (e.g. require: { builtin: ['*', '-fs', '-child_process'] }),
 negative entries are matched by exact module name in lib/builtin.js, so -fs removes only the builtin named
 fs and does not remove builtin subpaths such as fs/promises. Sandboxed code can therefore call
 require('fs/promises') or require('node:fs/promises') and reach the promise-based filesystem API despite
 fs being denied; node: prefix handling is likewise inconsistent (a -node:fs/promises entry does not block
 require('fs/promises')). Host file creation and writing were confirmed via fsp.writeFile(), and other
 fs/promises operations (cp, mkdir, rename, rm, rmdir, truncate, read operations, etc.) are also reachable.
 This issue is fixed in vm2 3.11.7. (CVE-2026-92958)

Solution

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