    CVE-2026-105216 (GCVE-0-2026-105216)

    Vulnerability from nvd – Published: 2026-10-04 17:09 – Updated: 2026-10-05 00:47

    Title
    go-micro before 6.0.0 Disabled TLS Certificate Verification via tls.Config Helper
    Summary
    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.
