Overview

Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the ftpcp() function when it processes server-supplied PASV host addresses without verifying them against the actual peer address. An attacker can cause connections to arbitrary hosts by supplying a malicious IP address and port in the FTP PASV response.
