Technical details
The SSRF vulnerability exists in Vvveb's oEmbed proxy, which performs server-side URL fetching and reflects the response. The vulnerability stems from an IPv4-only host resolution check that never inspects IPv6 addresses, allowing attackers to bypass private IP range validation. An authenticated admin-panel user (with site_admin role or higher) can craft requests using IPv6 literals or AAAA-only domains to access internal services and cloud metadata endpoints.
