## Technical details

A Local File Inclusion (LFI) vulnerability exists in the Select-Themes WaveRide theme for WordPress (versions up to and including 1.4) due to improper validation of user-supplied input used in PHP include or require statements (CWE-98). An unauthenticated remote attacker can exploit this by sending specially crafted requests to include local files from the server's filesystem. Successful exploitation can lead to the exposure of sensitive information, such as the wp-config.php file containing database credentials, or potentially remote code execution if the attacker can upload or influence the content of a local file. The vulnerability is addressed in version 1.5.
