An SMTP command injection issue exists in the transport `name` configuration option used in EHLO, HELO, and LHLO commands. The `name` parameter is concatenated directly into SMTP commands without sanitizing carriage return and line feed (CRLF) characters. An attacker capable of influencing this option can inject arbitrary SMTP commands, enabling unauthorized email sending, email spoofing, and phishing attacks. This occurs within the `lib/smtp-connection/index.js` file during connection initialization, where the ` sendCommand()` function writes the string directly to the socket.
