CVE-2026-18679

When kuma-dp is started against an HTTPS control plane and the operator did not pass a CA certificate, the data plane connects with TLS peer verification disabled, and the dataplane authentication token is sent over that unverified connection. An on-path actor can intercept the dataplane authentication token and impersonate the control plane to the data plane, injecting a forged bootstrap configuration and taking over the proxy.

Summary		(es) Cuyo kuma-dp se inicia contra un plano de control HTTPS y el operador no pasó un certificado CA, el plano de datos se conecta con la verificación de pares TLS deshabilitada, y el token de autenticación del plano de datos se envía a través de esa conexión no verificada. Un actor en la ruta puede interceptar el token de autenticación del plano de datos y suplantar al plano de control ante el plano de datos, inyectyo una configuración de arranque falsificada y tomyo el control del proxy.
