CVE-2026-105216

go-micro before 6.0.0 contains an improper certificate validation vulnerability that allows network attackers to impersonate services because the shared TLS helper sets InsecureSkipVerify to true by default. Man-in-the-middle attackers can present any certificate to intercept or modify gRPC transport, HTTP and RabbitMQ broker, and Consul or etcd registry traffic, including authentication tokens and credentials.
