CVE-2026-18678
When an operator adds an HTTPS control plane profile to kumactl without providing a CA certificate, kumactl disables TLS verification and sends API tokens over the unverified connection. An attacker on the network path between the operator and the control plane can intercept user or admin API tokens and then act against the control plane as that user.
