AI-suggested
Updated automation-controller packages that fix this issue are available for Ansible Automation Platform versions 2.5, 2.6, and 2.7 and should be applied. Version 2.4 will not receive a fix. Current mitigation options such as setting PROXY_IP_ALLOWED_LIST do not fully resolve the issue in Envoy deployments. The robust fix requires enabling the trusted-proxy shared-secret mechanism or changing the header selection logic to prefer the rightmost trusted entry. Until patched, users should be aware that log source IPs can be spoofed and interpret forensic data accordingly.
Description
CVE-2026-84718 is a vulnerability in Red Hat Ansible Automation Platform 2.5 for RHEL 8 where the automation-controller trusts the client-supplied X-Forwarded-For HTTP header without verifying it originated from a trusted proxy. This allows an attacker to spoof the source IP address recorded in audit and access logs, undermining the integrity of forensic and SIEM attribution. The flaw does not grant additional access or affect confidentiality or availability. Updated automation-controller packages fixing this issue are available for Ansible Automation Platform 2.5, 2.6, and 2.7, but not for 2.4.
