CVE-2025-9907Network attack vector

Credential disclosure via persisted test-mode headers

Published Feb 27, 2026 · Updated Feb 27, 2026

Information disclosure in Red Hat Ansible Automation Platform 2.5 and 2.6 allows remote authenticated users to read sensitive HTTP headers. The Event Stream API captures every incoming header in test_headers and persists the field without redacting Authorization or trusted-proxy values. Exposure requires test mode and event-stream read access; leaked headers remain visible and permit credential reuse when they contain valid tokens.
