There is no fixed version for Echo:latest node-nodemailer.

NVD Description

Note: Versions mentioned in the description apply only to the upstream node-nodemailer package and not the node-nodemailer package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

Nodemailer versions before 8.0.5 contain an SMTP command injection vulnerability in the transport name option used in EHLO/HELO commands. The name parameter is concatenated directly into SMTP commands without sanitizing carriage return and line feed characters, allowing attackers to inject arbitrary SMTP commands for email spoofing and phishing attacks.
