A vulnerability in the Joomla component com_dailymeals allows an attacker to perform a Local File Inclusion (LFI) attack. This vulnerability is caused by insufficient sanitization of user-supplied input in the 'controller' parameter of the 'index.php' script. An attacker can exploit this vulnerability by sending a specially crafted HTTP request containing directory traversal characters (e.g. '../') to the vulnerable server. This will allow the attacker to include and execute arbitrary local files on the server.
