Short explanation
Nodemailer versions contain a quadratic complexity denial of service vulnerability in the SMTP client reply parser within SMTPConnection._onData and isPartialResponse. A malicious SMTP server or on-path attacker can stream continuation lines without a completion line before authentication, blocking the Node.js event loop and exhausting memory.
This vulnerability allows attackers to lock the Node.js event loop and cause a denial of service via memory exhaustion. S0, S1
