CVE-2026-84718 Red Hat CVE debrief
A flaw in Red Hat Ansible Automation Platform's automation-controller allows client IP spoofing in audit and access logs due to unrestricted trust in the X-Forwarded-For header. This issue degrades the integrity of forensic and SIEM attribution but does not grant additional access. The vulnerability affects the automation-controller component of the platform, which is used for managing and orchestrating automation tasks. The lack of verification for the X-Forwarded-For header allows an attacker to forge the source IP address recorded in the Controller's audit and access logs, potentially impacting the accuracy of log analysis and incident response. Defenders should assess their log

Who should care
Security teams and administrators responsible for the deployment and maintenance of Red Hat Ansible Automation Platform should assess their exposure and verify the integrity of their audit and access logs.
Why it matters
CVE-2026-84718 allows client IP spoofing in Red Hat Ansible Automation Platform's automation-controller, degrading log integrity and potentially impacting forensic analysis and SIEM attribution. Defenders should verify log integrity, update incident response procedures, and monitor for potential IP spoofing attempts.
- Degraded integrity of forensic and SIEM attribution due to potential log tampering.
- Possible difficulty in accurately tracing the source of requests in audit and access logs.
- Need for verification of log integrity and potential updates to incident response procedures.
Technical summary
The automation-controller in Red Hat Ansible Automation Platform trusts the client-supplied X-Forwarded-For header without verification, allowing an attacker to forge the source IP address recorded in the Controller's audit and access logs. This issue degrades the integrity of forensic and SIEM attribution but does not grant additional access. The vulnerability affects the automation-controller component of the platform, which is used for managing and orchestrating automation tasks. The lack of verification for the X-Forwarded-For header allows an attacker to forge the source IP address recorded in the Controller's audit and access logs, potentially impacting the accuracy of log analysis and incident response.
Defensive priority
Defenders should prioritize verifying the integrity of their audit and access logs, especially in environments where log analysis is critical for security monitoring and incident response.
Recommended defensive actions
- Verify the configuration of automation-controller instances to ensure that the X-Forwarded-For header is properly validated.
- Implement additional logging and monitoring to detect potential IP spoofing attempts.
- Review and update incident response procedures to account for potential log tampering.
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
- Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
- Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
- Check relevant monitoring, detection, and logs for exposed assets that need extra review.
Evidence notes
The CVE record and source item provide details on the vulnerability, including its description, affected products, and references to vendor advisories. The vulnerability is caused by the automation-controller's trust in the client-supplied X-Forwarded-For header without verification, allowing an attacker to forge the source IP address recorded in the Controller's audit and access logs. The evidence is limited to the information provided in the CVE record and source item, and defenders should verify the integrity of their audit and
