Echo: vm2: security update to 3.11.7

critical Tenable Cloud Security Plugin ID 472228

Description

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

 - vm2 through 3.11.6 does not normalize `node:`-prefixed builtin specifiers when evaluating user-supplied
 negative (deny) entries in a NodeVM wildcard require policy. Although NodeVM strips the `node:` prefix
 during require() resolution, negative wildcard entries are matched by exact string comparison against the
 canonical builtin names, so a policy such as `new NodeVM({ require: { builtin: ['*',
 '-node:child_process'] } })` fails to deny the canonical `child_process` module. Sandboxed code can
 therefore obtain the host `child_process` builtin via `require('child_process')` or
 `require('node:child_process')`, gaining references to process-spawning APIs such as execSync and spawn,
 which is equivalent to host command-execution capability for untrusted sandbox code. Fixed in vm2 3.11.7.
 (CVE-2026-92957)

Solution

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