Debug mode, while useful during development and testing stages, can expose sensitive information such as server configuration, third-party modules, and other internal details of the application that can be exploited by attackers. In the worst-case scenario, it can lead to a serious security breach.
Make sure that debug mode is disabled in the production environment. This can be achieved by setting the debug configuration to false or 0 in the application’s configuration settings. For example, in CakePHP, use Config::write('debug', 0); or Configure::config('debug', false);, and in WordPress, use define('WP_DEBUG', false);.
