A server-side request forgery (SSRF) vulnerability exists in the Ansible Automation Platform automation-controller email notification backend. This flaw allows an authenticated user with notification-admin permission to specify arbitrary SMTP hosts and ports in email notification templates without validation, enabling internal network port scanning and potential credential exposure. The vulnerability affects the controller's ability to restrict connections to internal, loopback, link-local, or reserved addresses. When exploited, it can leak connection results and, if SMTP credentials are stored in shared templates, may lead to credential exfiltration.
