Vulnerability in Red Hat Ansible Automation Platform 2.7

CVSS 6.4 EPSS <1%1 agency advisoryNo fix listed yet

[ Description ]Official description

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