Description
Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-r7g4-qg5f-qqm2. This link is maintained to preserve external references.
Original Description
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.
