In the shipped\nproduction configuration, the Controller trusts the client-supplied X-Forwarded-For header as\nthe request's client IP without verifying that it originated from a trusted proxy, and selects\nthe leftmost (attacker-controlled) header value. As a result, an attacker can forge the source\nIP address recorded for their requests in the Controller's audit and access logs, degrading\nthe integrity of forensic and SIEM attribution. The flaw does not grant additional access.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **RHSA-2026:71114** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.5 for RHEL 8, Red Hat Ansible Automation Platform 2.5 for RHEL 9 · released 2026-09-23 · [advisory](https://access.redhat.com/errata/RHSA-2026:71114)\n- **RHSA-2026:71113** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.6 for RHEL 9 · released 2026-09-23 · [advisory](https://access.redhat.com/errata/RHSA-2026:71113)\n- **RHSA-2026:71179** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.6 · released 2026-09-23 · [advisory](https://access.redhat.com/errata/RHSA-2026:71179)\n- **RHSA-2026:71177** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.7 · released 2026-09-23 · [advisory](https://access.redhat.com/errata/RHSA-2026:71177)","depth":"sunlit","depthScore":24,"depthScoreParts":{"impact":23.7,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
