Description
## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-prgh-xp8r-p3m5. This link is maintained to preserve external references. ## Original Description Nodemailer versions 9.1.0 through 10.0.4 contain a quadratic time complexity vulnerability in the addressparser component when parsing email addresses with RFC 5322 comments. Attackers can craft malicious email headers with comment-separated atoms to consume excessive CPU and block the Node.js event loop for several seconds, causing denial of service.
