Technical details
A Local File Inclusion (LFI) vulnerability exists in the kutethemes Biolife theme (versions <= 3.2.3) for WordPress. The flaw stems from improper validation of user-supplied input used in PHP include or require statements (CWE-98). An attacker with 'Contributor' level privileges can exploit this over the network to include and execute local files on the server. This can lead to the disclosure 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 local file content. As of the advisory date, no official patch has been released.
