CVE-2026-84718 (GCVE-0-2026-84718)

Vulnerability from cvelistv5 – Published: 2026-09-23 19:40 – Updated: 2026-10-16 11:55

Title

Automation-controller: automation-controller: client ip spoofing in audit/access logs via unrestricted x-forwarded-for trust

Summary

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.

Severity

  "details": "A flaw was found in the Ansible Automation Platform automation-controller. In the shipped\nproduction configuration, the Controller trusts the client-supplied X-Forwarded-For header as\nthe request\u0027s 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\u0027s audit and access logs, degrading\nthe integrity of forensic and SIEM attribution. The flaw does not grant additional access.",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
