A flaw was found in the Ansible Automation Platform automation-controller. In the shipped
production configuration, the Controller trusts the client-supplied X-Forwarded-For header as
the request's client IP without verifying that it originated from a trusted proxy, and selects
the leftmost (attacker-controlled) header value. As a result, an attacker can forge the source
IP address recorded for their requests in the Controller's audit and access logs, degrading
the integrity of forensic and SIEM attribution.
The flaw does not grant additional access.
