Details

As written in the advisory (Markdown source, shown as plain text).

HashiCorp Consul 1.4.3 lacks server hostname verification for agent-to-agent TLS communication. In other words, the product behaves as if `verify_server_hostname` were set to false, even when it is actually set to true. This is fixed in 1.4.4.
