Description

Kong Kubernetes Ingress Controller (KIC) allows a user with namespace-scoped Secret creation privileges to cause a cluster-wide ingress configuration denial of service. KIC collects CA-certificate Secrets across all watched namespaces using a label selector alone, without ingress-class or namespace restrictions. The CA-certificate primary key is derived from a user-supplied field in the Secret. Duplicate CA-certificate IDs cause Kong Gateway to reject the entire configuration document and halting all ingress changes cluster-wide.
