Description
Coze Studio through 0.5.1 fails to restrict the server URL supplied when registering plugin tools, allowing authenticated users to make the backend fetch internal services. Attackers can construct plugin requests to access cloud metadata endpoints and internal services reachable only from the backend network, reading responses containing sensitive information.
