Echo: vm2: security update to 3.11.7

critical Tenable Cloud Security Plugin ID 472280

Description

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

 - vm2 versions 3.11.3 through 3.11.6 expose the host process's real https.globalAgent to sandboxed code when
 a NodeVM is explicitly configured to allow require('https'). The builtin loader wraps host modules in a
 read-only proxy, but method calls such as Agent.prototype.on() are forwarded to the underlying host
 object, so sandbox code can register a listener for the agent's 'free' event. When an unrelated host HTTPS
 request releases a pooled connection, the listener receives the live host request options and the host
 TLSSocket, allowing sandboxed code to read the host's Authorization header and private destination
 host/port, attach a data listener to the released socket and read subsequent host response bodies in
 plaintext, and issue attacker-chosen authenticated requests using the stolen credentials. The issue is
 fixed in 3.11.7. (CVE-2026-92940)

Solution

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