CVE-2026-84644

A flaw was found in Red Hat Ansible Automation Platform's automation- controller. The Thycotic Secret Server external credential plugin passes a user-supplied server URL to its SDK without validating the scheme, host, or IP range, and the plugin backend is executed synchronously within the automation controller web process. Using the external credential test endpoint, a user who holds only the use role on such a credential can override the stored server URL with an arbitrary internal address, causing the control plane to issue requests to internal services. Although the response is a generic error, response timing reveals whether internal hosts and ports are reachable, enabling internal network reconnaissance and a blind request-forgery primitive from the control plane, and each request can hold a web worker, affecting availability.
