{"apiVersion":"1.0","identifier":"CVE-2026-63642","description":"MagicMirror² is an open source modular smart mirror platform. Prior to 2.37.0, checkArticleUrl in defaultmodules/newsfeed/node_helper.js accepts the CHECK_ARTICLE_URL notification through the unauthenticated Socket.IO namespace /newsfeed and performs fetch(url, { method: -HEAD- }) without validating the attacker-controlled URL. The helper returns ARTICLE_URL_STATUS containing the URL and framing result, providing a response and timing oracle that can identify internal hosts and ports and trigger side effects on services that react to HEAD requests. This issue is fixed in version 2.37.0.","publishedAt":"2026-08-18T18:19:12","lastModifiedAt":"2026-08-19T16:18:39","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-63642","cvssScore":6.3,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/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":0.00364,"riskScore":0.65,"affectedProduct":"MagicMirror2","affectedVersions":"<2.37.0","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-63642","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-63642","en":"https://www.redsauce.net/en/cves/CVE-2026-63642","fr":"https://www.redsauce.net/fr/cves/CVE-2026-63642","pt":"https://www.redsauce.net/pt/cves/CVE-2026-63642","de":"https://www.redsauce.net/de/cves/CVE-2026-63642","sk":"https://www.redsauce.net/sk/cves/CVE-2026-63642","el":"https://www.redsauce.net/el/cves/CVE-2026-63642"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-63642"}}
