What is CVE-2026-63642?
CVE-2026-63642 is a medium-severity server-side request forgery vulnerability in MagicMirrorOrg MagicMirror, published on 18 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
Weakness: CWE-918
