The main security risk of using this module is only Information disclosure which includes infomation such as Server uptime, Individual request-response statistics and CPU usage of the working processes, Current HTTP requests, client IP addresses, requested paths, processed virtual hosts. , that could give a potential attacker information about how to attack the web server.
