CVE-2026-63641: MagicMirror Socket.IO module namespaces bypass configured IP whitelist and allow unauthenticated server-side actions

MagicMirror applies ipWhitelist only as Express middleware, but the Socket.IO server is attached directly to the HTTP server without equivalent IP allowlist, origin, or namespace authentication checks. In a documented common deployment where MagicMirror listens on a non-loopback interface but expects ipWhitelist to restrict access, an untrusted network client can connect directly to module Socket.IO namespaces and send arbitrary module-helper notifications. This allows unauthenticated server-side requests through default modules and can reach command execution in the default updatenotification helper when a third-party module update is pending and the attacker supplies the update command through the trusted socket configuration path.
