    CVE-2019-9764

    Published: 26 Mar 2019Last Modified: 8 Jul 2026

    Summary:

    Details: 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.
