go-wind-cms (GoWind) before 1.0.0 has a missing authorization vulnerability. The NewAuthorizer() function in app/admin/service/internal/data/data.go and app/app/service/internal/data/data.go returns a no-op authorization engine (noop.State{}), so the authz middleware always allows requests. Any authenticated user (regardless of role or tenant) can invoke administrative APIs such as deleting users, resetting passwords, and creating tenants.
