CVE-2026-63642 PUBLISHED

MagicMirror newsfeed Socket.IO notification allows blind server-side request forgery

Assigner: GitHub_M
Reserved: 17.07.2026 Published: 18.08.2026 Updated: 18.08.2026

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.
