  "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.",
