An issue was discovered in Responsive Filemanager through 9.14.0. In the dialog.php page the session variable $_SESSION'RF'\view_type\ wasn't sanitized if it was already set. This made stored XSS possible if one opens ajax_calls.php and uses the \view\ action and places a payload in the type parameter and then returns to the dialog.php page. This occurs because ajax_calls.php was also able to set the $_SESSION'RF'\view_type\ variable but there it wasn't sanitized.
