NVD Description

Note: Versions mentioned in the description apply only to the upstream node-nodemailer package and not the node-nodemailer package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

Nodemailer before 9.1.0 contains a quadratic time complexity vulnerability in the addressparser component that allows remote attackers to cause denial of service by supplying a crafted comma-separated address list. Attackers can send a single email with a large number of addresses to block the Node.js event loop for extended periods, consuming 100% CPU and freezing the process.
