What is CVE-2026-84718?
CVE-2026-84718 is a medium-severity vulnerability in Red Hat Ansible Automation Platform 2.5 for RHEL 8, published on 23 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official 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.
Weakness: CWE-348
