CVE-2025-9908 is a medium-severity flaw (CVSS 6.7) affecting ansible automation platform, ansible developer, ansible inside. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A flaw was found in the Red Hat Ansible Automation Platform, Event-Driven Ansible (EDA) Event Streams. This vulnerability allows an authenticated user to gain access to sensitive internal infrastructure headers (such as X-Trusted-Proxy and X-Envoy-*) and event stream URLs via crafted requests and job templates. By exfiltrating these headers, an attacker could spoof trusted requests, escalate privileges, or perform malicious event injection.
