Echo: vm2: security update to 3.11.7

high Tenable Cloud Security Plugin ID 473555

Description

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

 - vm2 before 3.11.7 (affected versions <= 3.11.6) does not enforce the VM({ timeout }) option on code
 executed outside the synchronous VM#run() call. The timeout only wraps the single call to _runScript() via
 doWithTimeout() in lib/vm.js, and FinalizationRegistry and WeakRef are exposed to sandboxed code
 unmodified (they are not among the hardened globals in lib/setup-sandbox.js). Sandboxed code can register
 a FinalizationRegistry cleanup callback against an object and then drop the only strong reference to it;
 vm.run() returns within the configured timeout, but when the V8 garbage collector later reclaims the
 object it invokes the sandboxed cleanup callback outside any vm2 timeout accounting. A busy loop in that
 callback blocks the host event loop for an unbounded period, resulting in denial of service. The time of
 invocation depends on the garbage collector (e.g. under memory pressure or with --expose-gc).
 (CVE-2026-92942)

Solution

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