Original description The description as published by the source.
Nodemailer from 3.0.0 before 10.1.4 contains a parsing flaw in addressparser that ends an RFC 5322 group at a semicolon inside quoted display names or comments. Attackers can submit crafted group addresses that conformant validators approve, redirecting mail to attacker-chosen recipients and bypassing recipient allow lists.
