Echo: vm2: security update to 3.11.7

critical Tenable Self-Hosted Container Security Plugin ID 473538

Description

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

 - vm2 versions 3.10.1 through 3.11.6 contain a sandbox escape reachable from a default `new VM()` sandbox
 when running on Node.js 26. WebAssembly.compileStreaming and WebAssembly.instantiateStreaming can produce
 a raw host-realm Promise that rejects with a host-realm error object; by controlling Symbol.species via
 Promise.prototype.finally, sandbox code receives that raw host error, walks from the host error
 constructor to the host Function constructor, and recovers the real host `process` object, gaining host
 Node.js capabilities (e.g. access to host modules such as fs) in the context of the process running the
 sandbox. No NodeVM, require permission, host object injection, or otherwise unsafe configuration is
 required. This is a bypass of the fix for GHSA-6j2x-vhqr-qr7q, which removed the JSPI entry points
 WebAssembly.promising and WebAssembly.Suspending. The issue is fixed in 3.11.7. (CVE-2026-92956)

Solution

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