Internal KUBERNETES_SERVICE_HOST IP address disclosure in /config endpoint

[zmotso]

Affected endpoint:
GET /config
Details:
While the delivery platform is running, the application periodically sends configuration requests (GET /config) and health checks (GET /clusters/main/healthz). While sending a GET /config request application reveals the KUBERNETES_SERVICE_HOST's internal IP address in the responses, intended for internal use within the cluster and backend systems. This exposure could allow attackers, in the event of a compromised pod, to target the system (for example, with DOS/DDOS attacks) or to learn the internal IP addressing schema.
