Echo: vm2: security update to 3.11.0+echo.2

high Tenable Cloud Security Plugin ID 457899

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 3.11.6, the bufferAllocLimit enforcement in
 lib/setup-sandbox.js does not cover Buffer.concat(list, totalLength) or Buffer.from(arrayLike) with an
 attacker-controlled length, allowing sandbox code to perform large synchronous host external-memory
 allocations that bypass the configured cap and can exhaust the host process. This issue is fixed in
 version 3.11.6. (CVE-2026-47683)

Solution

Update the vm2 library and its related packages to version 3.11.0+echo.2 or later.
