Technical details

A Local File Inclusion (LFI) vulnerability exists in the Mikado Core plugin for WordPress (versions 1.6 and earlier) due to improper validation of user-supplied input used in PHP include or require statements. An unauthenticated remote attacker can exploit this by sending a specially crafted request to include local files from the server. Successful exploitation can lead to the disclosure of sensitive information, such as the wp-config.php file, or potentially remote code execution if the attacker can upload or manipulate local files. The vulnerability is addressed in version 1.7.2.
