{"id":"CVE-2026-63641","state":"PUBLISHED","title":"MagicMirror Socket.IO module namespaces bypass configured IP whitelist and allow unauthenticated server-side actions","description":"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.","publishedAt":"2026-08-18T17:13:03.109Z","updatedAt":"2026-08-18T19:26:23.631Z","severity":{"score":2.3,"label":"Low","version":"4.0","vector":"CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:L/SI:L/SA:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["MagicMirrorOrg MagicMirror"],"affected":[{"vendor":"MagicMirrorOrg","product":"MagicMirror","versions":[{"version":"< 2.37.0","status":"affected"}]}],"references":["https://github.com/MagicMirrorOrg/MagicMirror/security/advisories/GHSA-w26r-fwg8-rcp3","https://github.com/MagicMirrorOrg/MagicMirror/pull/4169","https://github.com/MagicMirrorOrg/MagicMirror/commit/58c2a5e675a7d367b64d72e1d35680d202ff5c9f","https://github.com/MagicMirrorOrg/MagicMirror/releases/tag/v2.37.0"],"weaknesses":["CWE-284"],"ingestedAt":"2026-10-29T20:12:41.951Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/63xxx/CVE-2026-63641.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-63641","state":"PUBLISHED","datePublished":"2026-08-18T17:13:03.109Z","dateUpdated":"2026-08-18T19:26:23.631Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-07-17T14:11:15.483Z"},"containers":{"cna":{"title":"MagicMirror Socket.IO module namespaces bypass configured IP whitelist and allow unauthenticated server-side actions","descriptions":[{"lang":"en","value":"MagicMirror² is an open source modular smart mirror platform.
