How to fix?

Upgrade WinSCP to version 5.17.10 or higher.

Overview

WinSCP is a .NET wrapper around WinSCP’s scripting interface that allows your code to connect to a remote machine and manipulate remote files over SFTP, FTP, WebDAV, S3 and SCP sessions.

Affected versions of this package are vulnerable to Remote Code Execution (RCE). WinSCP allows remote attackers to execute arbitrary programs when the URL handler encounters a crafted URL that loads session settings. (For example, this is exploitable in a default installation in which WinSCP is the handler for sftp:// URLs.)
