Skipper: Unbounded Request Body Read in Admission Webhook Causes Memory Exhaustion DoS

Summary The Kubernetes admission webhook handler reads the entire request body using io.ReadAllr.Body without any size limit. Any client that can reach the webhook port within the cluster can send a multi-GB payload, causing the skipper process to exhaust memory and be OOM-killed. This disrupts a...
