DescriptionMagicMirror² is an open source modular smart mirror platform. Prior to 2.37.0, MagicMirror applies ipWhitelist only as Express middleware, while the Socket.IO server in js/server.js is attached directly to the HTTP server without equivalent IP allowlist, origin, or namespace authentication checks. In a documented non-loopback deployment that relies on ipWhitelist, an unauthenticated adjacent-network client can connect directly to module Socket.IO namespaces, and js/node_helper.js dispatches arbitrary events and payloads to socketNotificationReceived. The default newsfeed and calendar helpers can make server-side requests to attacker-selected URLs, while the default updatenotification helper can reach child_process.exec when a third-party module update is pending and the attacker supplies an update command through the socket CONFIG path. This can expose internal services, manipulate module-helper state, and conditionally execute commands. This issue is fixed in version 2.37.0.
