Echo: vm2: security update to 3.11.4

critical Tenable Cloud Security Plugin ID 459680

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, by combining
 Buffer.call.call({}.__lookupGetter__, Buffer, "__proto__"), Buffer.call.call({}.__lookupSetter__, Buffer,
 "__proto__"), and Node.js's ERR_INVALID_ARG_TYPE Error, the host's TypeError constructor can be obtained,
 which allows the escape from the sandbox. This allows attackers to run arbitrary code. This issue has been
 patched in version 3.11.4. (CVE-2026-47131)

Solution

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