CVE-2026-84721: Red Hat Ansible Automation Platform server-side request forgery in email backend

CVE-2026-84721 · Severity: medium · CVSS 6.4 · Published 2026-09-23

Red Hat Ansible Automation Platform's email notification system fails to validate SMTP server addresses, allowing authenticated users with notification-admin permissions to redirect email traffic to internal servers. An attacker can exploit this to scan internal networks and ports, or intercept stored email credentials, gaining access to sensitive infrastructure behind the firewall.

Technical details

A server-side request forgery vulnerability exists in the Ansible Automation Platform automation-controller email notification backend where user-supplied SMTP host and port parameters from notification templates are passed directly to the SMTP client without validating against internal, loopback, link-local, or reserved address ranges. An authenticated user with organization notification-admin permission can modify email templates to target arbitrary internal addresses, triggering test notifications that provide a three-state oracle (open/closed/filtered) for internal network port scanning and potentially exfiltrate stored SMTP credentials to attacker-controlled servers.
