{"id":"CVE-2026-63641","aliases":["GHSA-w26r-fwg8-rcp3"],"url":"https://o3.security/vulnerability/CVE-2026-63641","summary":"MagicMirror Socket.IO module namespaces bypass configured IP whitelist and allow unauthenticated server-side actions","details":"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.","published":"2026-08-18T17:13:03.109Z","modified":"2026-08-19T03:48:28.805807652Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"magicmirror","fixedVersion":"2.37.0"}],"fix":{"url":"https://github.com/MagicMirrorOrg/MagicMirror/commit/58c2a5e675a7d367b64d72e1d35680d202ff5c9f","label":"MagicMirrorOrg/MagicMirror@58c2a5e"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63641.json"},{"type":"FIX","url":"https://github.com/MagicMirrorOrg/MagicMirror/commit/58c2a5e675a7d367b64d72e1d35680d202ff5c9f"},{"type":"FIX","url":"https://github.com/MagicMirrorOrg/MagicMirror/pull/4169"},{"type":"WEB","url":"https://github.com/MagicMirrorOrg/MagicMirror/releases/tag/v2.37.0"},{"type":"ADVISORY","url":"https://github.com/MagicMirrorOrg/MagicMirror/security/advisories/GHSA-w26r-fwg8-rcp3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-63641"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T03:48:28.805807652Z"}}
