{"apiVersion":"1.0","identifier":"CVE-2026-63643","description":"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.","publishedAt":"2026-08-18T18:19:12","lastModifiedAt":"2026-08-19T19:17:22","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-63643","cvssScore":6.3,"cvssVector":"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","epssProbability":0.00474,"riskScore":0.66,"affectedProduct":"MagicMirror2","affectedVersions":"<2.37.0","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-63643","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-63643","en":"https://www.redsauce.net/en/cves/CVE-2026-63643","fr":"https://www.redsauce.net/fr/cves/CVE-2026-63643","pt":"https://www.redsauce.net/pt/cves/CVE-2026-63643","de":"https://www.redsauce.net/de/cves/CVE-2026-63643","sk":"https://www.redsauce.net/sk/cves/CVE-2026-63643","el":"https://www.redsauce.net/el/cves/CVE-2026-63643"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-63643"}}
