CVE-2026-84721

*** Pendiente de traducción *** A server-side request forgery flaw was found in the Ansible Automation Platform<br /> automation-controller email notification backend. The email backend passes the user-supplied SMTP<br /> host and port from a notification template directly to the SMTP client without validating that<br /> the target is not an internal, loopback, link-local, or reserved address. An authenticated user<br /> with organization notification-admin permission can create or modify an email notification<br /> template pointing at an arbitrary internal address, trigger a test, and have the controller task<br /> process open a raw TCP connection to that address. The resulting connection error is reflected<br /> back through the notification record, providing a three-state internal port-scan oracle (open,<br /> closed, filtered) over the control-plane&amp;#39;s cluster network, including the in-cluster Kubernetes<br /> API. When a shared organization template holds a stored SMTP password, redirecting the host can<br /> also cause that credential to be transmitted to an attacker-controlled server.
