Sensitive Data Exposure via test_headers in Red Hat Ansible EDA Event Stream API
CVE-2025-9907 Published on February 27, 2026

Event-driven-ansible: event stream test mode exposes sensitive headers in aap eda
A flaw was found in the Red Hat Ansible Automation Platform, Event-Driven Ansible (EDA) Event Stream API. This vulnerability allows exposure of sensitive client credentials and internal infrastructure headers via the test_headers field when an event stream is in test mode. The possible outcome includes leakage of internal infrastructure details, accidental disclosure of user or system credentials, privilege escalation if high-value tokens are exposed, and persistent sensitive data exposure to all users with read access on the event stream.
