SCA: security update for vm2 (GHSA-mpf8-4hx2-7cjg)

high Tenable Cloud Security Plugin ID 441476

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 3.11.0, a sandbox boundary violation in vm2 allows
 host object identity to cross into the sandbox through host Promise resolution. When a host-side Promise
 that resolves to a host object is exposed to the sandbox, the value delivered to the sandbox .then()
 callback preserves host identity. This allows the sandbox to interact with the host object directly,
 including performing identity checks using host-side WeakMap and mutating host object state from inside
 the sandbox. This behavior occurs because the Promise fulfillment wrapper uses ensureThis() instead of the
 stronger cross-realm conversion path (from() / proxy wrapping). If no prototype mapping is found,
 ensureThis() returns the original object. As a result, objects resolved by host Promises can cross the
 sandbox boundary without proper isolation. This vulnerability is fixed in 3.11.0. (CVE-2026-44000)

Solution

Update the vm2 library and its related packages to version 3.11.0 or later.
