A crafted server-function URL can therefore return attacker-controlled HTML from the application\u0027s origin; when a visitor opens the URL, the injected script can access same-origin data and issue requests with the visitor\u0027s authority. This issue is fixed in @tanstack/start-server-core 1.169.39, @tanstack/react-start 1.168.60, @tanstack/solid-start 1.168.57, and @tanstack/vue-start 1.168.56."
