HashiCorp Consul and Consul Enterprise 1.8.0 through 1.9.14, 1.10.7, and 1.11.2 has Uncontrolled Resource Consumption. Clusters with at least one ingress gateway configured may allow a user with service:write
permission to register a specifically-defined service that can cause the Consul server to panic and shutdown. Versions 1.9.15, 1.10.8, and 1.11.3 contain patches for the problem.
