CVE-2026-30828Public exploitNetwork attack vector

Authenticated local file disclosure via webhook URL

Published Mar 7, 2026 · Updated Mar 7, 2026

SSRF in Wallos before 4.6.2 allows remote authenticated users to read local system files through a crafted webhook-test URL. The testwebhooknotifications.php endpoint passes the JSON url value directly to cURL's CURLOPT_URL without validating its scheme or destination, so a file URL returns server-side file contents. Access requires a logged-in session; the demonstrated consequence is file disclosure, not file modification or service interruption.
