Description

Vvveb 1.0.8.6 contains an incomplete server-side request forgery fix that allows authenticated admin users to bypass DNS pinning by requesting non-443 URLs. Attackers can supply a rebinding hostname to the editor oEmbedProxy url parameter to read loopback services, internal panels, and cloud metadata credentials.
