## Overview

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.
