CVE-2026-55232Public exploitNetwork attack vectorHinoki check available

Internal data disclosure via IPv6 SSRF guard bypass

Published Oct 1, 2026 · Updated Oct 1, 2026

SSRF in the editor oEmbed proxy in givanz Vvveb 1.0.8.5 and earlier allows remote authenticated users to read internal HTTP responses. The validateUrl() guard checks only IPv4 addresses, so an IPv6 literal or AAAA-only host passes its private-range check before getUrl() fetches the URL and the proxy returns the response body. Admin-panel access with the site_admin role or higher is required; exposed responses can include internal service data or cloud metadata credentials.
