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."}],"affected":[{"vendor":"Red Hat","product":"Red Hat Ansible Automation Platform 2.7","collectionURL":"https://catalog.redhat.com/software/containers/","packageName":"ansible-automation-platform-27/controller-rhel9","defaultStatus":"affected","versions":[{"version":"1789580684","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/a:redhat:ansible_automation_platform:2.7::el9"]},{"vendor":"Red Hat","product":"Red Hat Ansible Automation Platform 2","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"automation-controller","defaultStatus":"affected","cpes":["cpe:/a:redhat:ansible_automation_platform:2"]}],"references":[{"url":"https://access.redhat.com/errata/RHSA-2026:71177","name":"RHSA-2026:71177","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/security/cve/CVE-2026-84721","tags":["vdb-entry","x_refsource_REDHAT"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2527220","name":"RHBZ#2527220","tags":["issue-tracking","x_refsource_REDHAT"]}],"datePublic":"2026-09-23T00:00:00.000Z","problemTypes":[{"descriptions":[{"cweId":"CWE-918","description":"Server-Side Request Forgery (SSRF)","lang":"en","type":"CWE"}]}],"x_redhatCweChain":"CWE-918: Server-Side Request Forgery (SSRF)","timeline":[{"lang":"en","time":"2026-09-02T01:43:36.658Z","value":"Reported to Red Hat."},{"lang":"en","time":"2026-09-23T00:00:00.000Z","value":"Made public."}],"providerMetadata":{"orgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","shortName":"redhat","dateUpdated":"2026-09-24T06:09:45.407Z"},"x_generator":{"engine":"cvelib 1.8.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-24T13:59:00.476952Z","id":"CVE-2026-84721","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-24T15:05:17.927Z"}}]}}
