Detailsinfo

A vulnerability was found in Red Hat Ansible Automation Platform (version now known). It has been rated as very critical. This issue affects some unknown processing of the component Provisioning Callback/Activity Stream. The manipulation of the argument host_config_key/X-Forwarded-For with an unknown input leads to a privileges management vulnerability. Using CWE to declare the problem leads to CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at access.redhat.com. The identification of this vulnerability is CVE-2026-84474 since 09/01/2026. The exploitation is known to be easy. The attack may be initiated remotely. Technical details are known, but no exploit is available. The price for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 09/23/2026). MITRE ATT&CK project uses the attack technique T1068 for this issue.
