A request for `/../outside.txt` escapes public_dir, and percent-encoding the dots reaches the same file.\n\nThe handler is off by default. An application is affected once it names File in route_handlers and sets static_handler to 0, which otherwise refuses a dot segment before the route runs.\n\nAny file the worker process can read is served to an unauthenticated request, including the application's config.yml above public_dir."
