## Technical details

A Local File Inclusion (LFI) vulnerability exists in the Kastell theme for WordPress (versions <= 2.0) due to improper validation of user-supplied path input. An unauthenticated remote attacker can exploit this by sending specially crafted requests to include and execute local files on the server. This can lead to the disclosure of sensitive information, such as wp-config.php, or remote code execution if the attacker can upload or find a controllable file on the system. The vulnerability is addressed in version 2.0.1.
