The email backend passes the user-supplied SMTP\nhost and port from a notification template directly to the SMTP client without validating that\nthe target is not an internal, loopback, link-local, or reserved address. An authenticated user\nwith organization notification-admin permission can create or modify an email notification\ntemplate pointing at an arbitrary internal address, trigger a test, and have the controller task\nprocess open a raw TCP connection to that address. The resulting connection error is reflected\nback through the notification record, providing a three-state internal port-scan oracle (open,\nclosed, filtered) over the control-plane's cluster network, including the in-cluster Kubernetes\nAPI. When a shared organization template holds a stored SMTP password, redirecting the host can\nalso cause that credential to be transmitted to an attacker-controlled server."
