{"id":"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.","aliases":["GHSA-w6x9-28jw-hq7j"],"modified":"2026-08-21T03:30:41.412936370Z","published":"2026-08-18T17:18:52.556Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-441","CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63643.json"},"references":[{"type":"WEB","url":"https://github.com/MagicMirrorOrg/MagicMirror/releases/tag/v2.37.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63643.json"},{"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"},{"type":"FIX","url":"https://github.com/MagicMirrorOrg/MagicMirror/commit/58c2a5e675a7d367b64d72e1d35680d202ff5c9f"},{"type":"FIX","url":"https://github.com/MagicMirrorOrg/MagicMirror/pull/4169"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/magicmirrororg/magicmirror","events":[{"introduced":"0"},{"fixed":"58c2a5e675a7d367b64d72e1d35680d202ff5c9f"},{"fixed":"4b4a59534f7da01e4030e46029fe9dd649a7675e"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"2.37.0"}]}}],"versions":["v2.36.0","v2.35.0","v2.34.0","v2.33.0","v2.32.0","v2.31.0","v2.30.0","v2.29.0","v2.28.0","v2.27.0","v2.26.0","v2.25.0","v2.24.0","v2.23.0","v2.22.0","v2.21.0","v2.20.0","v2.19.0","v2.18.0","v2.17.1","v2.17.0","v2.16.0","v2.15.0","v2.14.0","v2.13.0","v2.12.0","v2.11.0","v2.10.1","v2.10.0","v2.9.0","v2.8.0","v2.7.1","v2.6.0","v2.7.0","v2.5.0","v2.2.2","v2.4.1","v2.4.0","v2.3.1","v2.3.0","v2.2.1","V2.2.1","v2.2.0","v2.1.3","v.2.1.3","v2.1.2","v2.1.1","v2.1.0","v2.0.5","v2.0.4","v2.0.3","v2.0.2","v2.0.1","v2.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-63643.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N"}]}
