Authenticated internal-network access via unchecked editor URL
Published Aug 4, 2025 · Updated Aug 5, 2025
Server-side request forgery in givanz Vvveb 1.0.0 through 1.0.5 allows remote authenticated users to access internal services. The Drag-and-Drop Editor fetches the url parameter from the server without restricting loopback or internal destinations and returns the fetched content. High-privileged editor access is required, and successful requests can disclose reachable responses or enumerate internal ports.
