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.","cvss_v4":{"vector":"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","score":6.3},"cvss_v3":null,"cwes":["CWE-918"],"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-998g-7v5w-cr7g","https://github.com/MagicMirrorOrg/MagicMirror/security/advisories/GHSA-998g-7v5w-cr7g"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:26.291718493+00:00"},"epss":{"cve":"CVE-2026-63642","score":0.00496,"percentile":0.42274,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-998g-7v5w-cr7g","url":"https://osv.dev/vulnerability/GHSA-998g-7v5w-cr7g","summary":"MagicMirror newsfeed Socket.IO notification allows blind server-side request forgery","modified":"2026-08-18T17:41:04.517510Z","packages":[{"ecosystem":"npm","name":"magicmirror","purl":"pkg:npm/magicmirror","ranges":["<2.37.0"],"fixed":["2.37.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
