https://github.com/erlang/otp/security/advisories/GHSA-24cv-hwgr-37fq reports:

The FTP client in passive mode did not validate the IP address returned in the server's response, allowing a compromised or malicious server to redirect the data connection to an arbitrary host. This enables server-side request forgery (SSRF) and FTP bounce attacks.
