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.","state":0,"publishedAt":"2026-08-18T18:19:12.26+00:00","modifiedAt":"2026-10-22T22:10:00.25+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":6.3,"severity":"MEDIUM"}],"references":["https://github.com/MagicMirrorOrg/MagicMirror/commit/58c2a5e675a7d367b64d72e1d35680d202ff5c9f","https://github.com/MagicMirrorOrg/MagicMirror/pull/4169","https://github.com/MagicMirrorOrg/MagicMirror/releases/tag/v2.37.0","https://github.com/MagicMirrorOrg/MagicMirror/security/advisories/GHSA-w6x9-28jw-hq7j"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-63643","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-441","CWE-918"],"productCriteria":[],"sourceDates":{"published":"2026-08-18T18:19:12.260","lastModified":"2026-10-22T22:10:00.250"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
