## Description

Kuma is a modern Envoy-based service mesh that can run on every cloud across both Kubernetes and VMs. Prior to 2.7.26, 2.9.16, 2.11.14, 2.12.11, and 2.13.7, Universal mode kuma-dp connections to an HTTPS control plane disable TLS peer verification when --ca-cert-file is not supplied and KUMA_CONTROL_PLANE_CA_CERT is unset. The dataplane authentication token is sent over the unverified connection, allowing an on-path attacker to intercept the token, impersonate the control plane, inject a forged bootstrap configuration, and take over the proxy. Standard Kubernetes installations created by kumactl install control-plane or the official Helm chart are unaffected because the mutating admission webhook injects KUMA_CONTROL_PLANE_CA_CERT into each sidecar. This issue is fixed in versions 2.7.26, 2.9.16, 2.11.14, 2.12.11, and 2.13.7.
