Answer in brief

CVE-2026-84718 records a Medium severity (CVSS 4.3) vulnerability in Automation-controller: automation-controller: client ip spoofing in audit/access logs via unrestricted x-forwarded-for trust. The current sources do not mark it as known exploited. The current feed maps Red Hat/ansible-automation-platform-26/controller-rhel9 (generic), Red Hat/ansible-automation-platform-27/controller-rhel9 (generic). Check affected ranges and fixed versions before updating.

Why this deserves its current priority

CVSS is 4.3. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Red Hat/ansible-automation-platform-26/controller-rhel9, Red Hat/ansible-automation-platform-27/controller-rhel9.
  2. 2Review the reported fix. Source-reported workaround: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability. Note that merely populating PROXY_IP_ALLOWED_LIST does not fully resolve the issue in the shipped Envoy-fronted deployment, because the leftmost (attacker-controlled) X-Forwarded-For entry is still selected as the client IP, and the trusted-proxy shared-secret mechanism (a valid HTTP_X_TRUSTED_PROXY header), which makes Controller prefer the trusted rightmost X-Forwarded-For entry, is not enabled by default. Updated automation-controller packages that address this flaw are available for the Ansible Automation Platform 2.5, 2.6, and 2.7 update streams; the Ansible Automation Platform 2.4 stream will not receive a fix for this issue.

Upstream source description

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.
