AI risk analysis

Summary
This flaw allows sandboxed code to access and manipulate host HTTPS requests, enabling credential theft and unauthorized request issuance.
Exploitability
Exploitation requires explicit NodeVM configuration to allow 'https' and access to the host's globalAgent. The attacker must have the ability to inject code into the sandbox.
Blast radius
If exploited, the impact could be severe, including unauthorized access to sensitive data and the ability to perform actions on behalf of the host process.
Detection
No reliable host or network indicator is derivable from the published description.
Prioritized remediation
Upgrade to vm2 version 3.11.7 or later.

NVD description

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.
