    <h1>Chrome Views Component Vulnerability PoC</h1>
    <p>This PoC demonstrates the Views component privilege escalation.</p>
    <p>Prerequisites: Renderer process must already be compromised.</p>
    
    <!-- Trigger mechanism for Views component vulnerability -->
    <div id="trigger" style="display:none;">
        <script>
            // Simulate the Views component interaction
            function triggerViewsVulnerability() {
                // This would require actual renderer compromise
                // The vulnerability allows privilege escalation through Views
                console.log("Attempting Views component exploitation...");
                
                // Example trigger mechanism (requires compromised renderer)
                const maliciousElement = document.createElement('div');
                maliciousElement.setAttribute('data-views-trigger', 'true');
                document.body.appendChild(maliciousElement);
                
                // The actual exploit would leverage Views API misuse
                // to escalate privileges from compromised renderer
            }
            
            // Execute when page loads
            window.onload = function() {
                setTimeout(triggerViewsVulnerability, 1000);
            };
        </script>
    </div>
    
    <p><strong>Note:</strong> This is a conceptual PoC. Actual exploitation requires a pre-compromised renderer process.</p>
    <p><strong>Mitigation:</strong> Update Chrome to version 142.0.7444.137 or later.</p>
