EUVD-2026-87672

Nodemailer is a Node.js email-sending library. In versions = 9.1.0 and 10.0.9, the address parser src/addressparser mishandles addresses whose local-part is a quoted string and that are followed by RFC 5322 comments, allowing trailing comment-separated domain atoms to be retained in the normalize...

CVE-2026-92597

A flaw was found in Nodemailer. This vulnerability allows a remote attacker to bypass email domain validation due to incorrect parsing of RFC 5322 comments in email addresses. Specifically, a malformed comment can cause Nodemailer to misinterpret the recipient's domain, leading to the delivery of...

CVE-2026-90776

Nodemailer versions 9.1.0 through 10.0.4 contain a quadratic time complexity vulnerability in the addressparser component when parsing email addresses with RFC 5322 comments. Attackers can craft malicious email headers with comment-separated atoms to consume excessive CPU and block the Node.js...
