CVE-2026-110870
Last modified
CVE-2026-110870 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. 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 characters reach envelope.to and RCPT TO, causing rejected delivery or parser interpretation conflicts that bypass domain allow-lists.. EPSS estimates a 0.22% chance of exploitation in the next 30 days.
