Nodemailer versions 5.0.0 through 10.0.1 have a vulnerability in their DNS caching mechanism where the cache key is only the DNS host, but cache entries also store a caller-specific TLS servername. This causes the wrong SNI value to be sent when multiple TLS transports resolve the same host with different servernames, leading to incorrect certificate validation. An attacker able to prime the cache can cause a victim to connect to the attacker's TLS host and accept a malicious certificate, potentially exposing SMTP credentials. This issue is fixed in Nodemailer version 10.0.2. Join the discussion | GCVE Database | 09/26/2026, 15:31:22 UTC Added: 09/27/2026, 04:30:19 UTC |
