How to fix?

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 before 8.0.9 fails to sanitize carriage return and line feed characters in list comment fields, allowing attackers to inject arbitrary message headers. An attacker with control over list.*.comment parameters can inject CRLF sequences to create additional headers in generated RFC822 messages, altering mail client behavior and message semantics.
