Nodemailer from 3.0.0 before 10.1.4 contains an address parsing vulnerability in addressparser that ends an angle-addr at a '>' inside a quoted local part, comment or domain literal. Attackers can submit addresses that validate as an allowed domain but are delivered to an attacker-controlled domain, bypassing recipient allow lists and disclosing message content.
