LWS Cleaner < 2.4.2 - Admin+ Arbitrary File Deletion

Description

The plugin is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'lws_cl_delete_file' function. This makes it possible for authenticated attackers, with Administrator-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).
