AI-suggested
A patch is available in Nodemailer version 7.0.7 that fixes the parsing logic to correctly handle quoted local-parts per RFC 5321/5322. Users should upgrade to version 7.0.7 or later. Currently, no alternative mitigations exist. It is recommended to reject local-parts containing embedded '@' characters unless fully compliant with quoting rules.
Description
Nodemailer contains a vulnerability in its email parsing logic where quoted local-parts containing '@' characters are improperly handled. This causes emails to be misrouted to unintended external domains instead of the intended recipient, violating RFC 5321/5322 standards. The flaw can lead to data leakage, filter evasion, and bypass of domain-based access controls in downstream applications. The vulnerability affects Nodemailer versions prior to 7.0.7 and has been fixed in version 7.0.7.
