What is CVE-2019-25779?

The Diarise theme by WooThemes prior to version 1.5.9 includes a vulnerability that allows unauthenticated attackers to read arbitrary files via the calendar parameter in download.php. By exploiting this flaw, it is possible for adversaries to gain access to sensitive files on the server, such as /etc/passwd. This exploitation can occur through specially crafted GET requests that utilize file:// scheme paths, posing a significant risk to user data and server integrity.
