MEDIUMPre-NVD 6.36.3—
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.5%, top 61% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
