Summary
Nodemailer before 8.0.8 disables TLS certificate verification in lib/fetch/index.js through rejectUnauthorized: false, allowing attackers to intercept OAuth2 token requests. Attackers in a machine-in-the-middle position can capture OAuth client secrets, refresh tokens, and access tokens transmitted over compromised HTTPS connections.
A flaw was found in Nodemailer where it disables Transport Layer Security (TLS) certificate verification. A remote attacker, positioned between the user and the server (a machine-in-the-middle attack), could exploit this by intercepting OAuth2 token requests.
