CVE-2026-121424 Nodemailer 3.0.0 before 10.1.4 Address Parsing Bypass via Nested Comments

Nodemailer from 3.0.0 before 10.1.4 contains an address parsing vulnerability in addressparser that allows remote attackers to redirect recipients by ending nested RFC 5322 comments at the first closing parenthesis. Attackers can submit addresses whose nested comment hides an attacker address,...

CVE-2026-121424

The Nodemailer library (versions 3.0.0 before 10.1.4) contains an address parsing vulnerability in the addressparser component. The root cause is that the parser incorrectly handles nested RFC 5322 comments by ending them at the first closing parenthesis. This allows remote attackers to craft add...

EUVD-2026-101753

Nodemailer from 3.0.0 before 10.0.13 contains an improper input validation vulnerability in its address parser that fails to strip RFC 5322 comments inside angle-bracket addresses. Attackers can supply recipients like a display name with a parenthesized comment in the domain, so illegal character...

CVE-2026-110870 Nodemailer before 10.0.13 Improper Input Validation via Angle-Bracket Address Comments

Nodemailer from 3.0.0 before 10.0.13 contains an improper input validation vulnerability in its address parser that fails to strip RFC 5322 comments inside angle-bracket addresses. Attackers can supply recipients like a display name with a parenthesized comment in the domain, so illegal character...

CVE-2026-110870

The Nodemailer library (versions 3.0.0 to before 10.0.13 ) is vulnerable to an improper input validation flaw in its address parser. The vulnerability stems from a failure to strip RFC 5322 comments found inside angle-bracket addresses. An attacker can provide a recipient containing a display nam...

CVE-2026-110870 Nodemailer before 10.0.13 Improper Input Validation via Angle-Bracket Address Comments

Nodemailer from 3.0.0 before 10.0.13 contains an improper input validation vulnerability in its address parser that fails to strip RFC 5322 comments inside angle-bracket addresses.

GHSA-PRGH-XP8R-P3M5 Nodemailer addressparser: O(n^2) on comment-joined addresses enables a remote DoS (reachable via mailparser)

Summary nodemailer/lib/addressparser parses one shape of address in On^2 time. A single 640 KB address value blocks the Node.js event loop for roughly 7 seconds. And it is reachable without auth: mailparser feeds inbound email headers straight into this parser, so one crafted email is enough to...

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...

SUSE 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...
