Detailsinfo

A vulnerability has been found in MagicMirrorOrg MagicMirror up to 2.36.9 and classified as critical. This vulnerability affects the function socketNotificationReceived of the file js/node_helper.js of the component Socket.IO server. The manipulation of the argument CONFIG with an unknown input leads to a server-side request forgery vulnerability. The CWE definition for the vulnerability is CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

MagicMirror² 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.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-63641 since 07/17/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are known technical details, but no exploit is available.

Upgrading to version 2.37.0 eliminates this vulnerability.
