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 9.1.0 fails to apply UTS-46 normalization when encoding international domain names, causing the domain resolver to compute a different Punycode A-label than standards-compliant parsers. Attackers can craft recipient addresses with invisible characters or compatibility mappings that pass domain allow-list checks but are delivered to attacker-controlled domains via SMTP.
