{"id":"CVE-2026-63642","summary":"MagicMirror newsfeed Socket.IO notification allows blind server-side request forgery","details":"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.","aliases":["GHSA-998g-7v5w-cr7g"],"modified":"2026-09-10T03:30:35.547969723Z","published":"2026-08-18T17:22:02.733Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63642.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-918"]},"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-2026-63642.json"},{"type":"ADVISORY","url":"https://github.com/MagicMirrorOrg/MagicMirror/security/advisories/GHSA-998g-7v5w-cr7g"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-63642"},{"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-2026-63642.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:N/VI:N/VA:N/SC:L/SI:N/SA:N"}]}
