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.","categories":["Operating systems"],"product":"Red Hat Ansible Automation Platform 2.7","vendor":"Red Hat","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-84721","source_modified_at":"2026-10-16T11:55:30.534Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Ansible Automation Platform 2.7","vendor":"Red Hat","versions":[{"version":"1789580684","lessThan":"*","versionType":"rpm","status":"unaffected"}],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-84721","source_modified_at":"2026-10-16T11:55:30.534Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Ansible Automation Platform 2","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-84721","source_modified_at":"2026-10-16T11:55:30.534Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Ansible Automation Platform 2","vendor":"Red Hat","versions":[],"defaultStatus":"affected"}],"fixed_versions":[],"cvss":6.4,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00171,"percentile":0.06215,"score_date":"2026-10-23"},"published_at":"2026-09-23T19:40:38.686Z","modified_at":"2026-10-16T11:55:30.534Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-84721","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T11:55:30.534Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-84721","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://access.redhat.com/errata/RHSA-2026:71177","tags":["vendor-advisory","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://access.redhat.com/security/cve/CVE-2026-84721","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2527220","tags":["issue-tracking","x_refsource_REDHAT"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-24T13:59:00.476952Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-16T11:55:30.534Z","content_hash":"463bf34cb62d68bc53fa9b2bd5af99ce765d93b7e047f1287614a7a87a85a733"}}
