Every CVE for givanz Vvveb

Exploited in the last 30 days

Vvveb is a powerful and easy to use CMS with page builder to build websites, blogs or ecommerce stores. Prior to version 1.0.8.6, Vvveb's SSRF guard resolves a host with an IPv4-only function and never inspects IPv6, so any host that lacks an A record passes a private-range check. Editor oEmbed proxy fetches an attacker-supplied URL server side and reflects a response body, so an authenticated admin-panel user (default role site_admin or higher) can read internal-only services and cloud metadata, including IAM credentials, using an IPv6 literal or a domain that carries only an AAAA record. This issue has been patched in version 1.0.8.6.
