ProjectSend r2029 contains a reflected cross-site scripting vulnerability in thumbnails-regenerate.php that allows remote attackers to inject arbitrary HTML and JavaScript by supplying unsanitized values in the start_date and end_date GET parameters, which are echoed unescaped into HTML attribute values.
