| Doc Text: |
A flaw was found in Nodemailer. A remote attacker can bypass domain allow-lists or cause email delivery failures by submitting specially crafted recipient addresses. Because the address parser fails to properly strip parenthesized comments within formatted email addresses, unvalidated characters are forwarded to mail transfer envelope commands.
