Weak configuration vulnerability in File Manager 7.2.1

The File Manager plugin for WordPress has a security issue that exposes sensitive information. This problem affects all versions up to 7.2.1. The backup filenames for this plugin use a timestamp and 4 random digits, but they are not random enough. As a result, attackers who are not logged in can access important data, such as site backups. This can happen if the .htaccess file in the directory does not prevent unauthorized access.
