{"id":"CVE-2026-63643","aliases":["GHSA-w6x9-28jw-hq7j"],"url":"https://o3.security/vulnerability/CVE-2026-63643","summary":"MagicMirror: ssrf calendar .js","details":"MagicMirror² is an open source modular smart mirror platform. Prior to 2.37.0, the ADD_CALENDAR handler in defaultmodules/calendar/node_helper.js accepts an attacker-controlled URL, authentication data, and selfSignedCert setting through the unauthenticated Socket.IO namespace /calendar. The handler passes these fields to CalendarFetcher, causing a server-side request without SSRF validation and optionally disabling TLS verification. When the response is valid iCal, CALENDAR_EVENTS returns parsed event data to the attacker, allowing internal-service response data to be exfiltrated; other responses still provide a blind request and timing primitive. This issue is fixed in version 2.37.0.","published":"2026-08-18T17:18:52.556Z","modified":"2026-08-19T03:48:34.913646895Z","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-2026-63643.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-w6x9-28jw-hq7j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-63643"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T03:48:34.913646895Z"}}
