CVE-2026-84474

CRITICAL 9.9

Published 2026-09-23 · Last modified 2026-09-24

A flaw was found in Red Hat Ansible Automation Platform's automation- controller. The provisioning-callback secret (host_config_key) is exposed to users holding only the read-level view_jobtemplate permission -- both in the job template API representation and in the activity stream -- and the provisioning callback endpoint trusts a client-supplied X-Forwarded-For header to determine the calling host when the controller is deployed behind the AAP gateway with an empty proxy allow-list. By reading the secret and spoofing X-Forwarded-For to match any host in the job template's inventory, a minimally privileged or unauthenticated remote attacker can launch the job template against arbitrary managed hosts using the job template's credentials, resulting in privilege escalation and remote code execution on managed hosts.
