CVE-2025-9907 | 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.

Base score Version Severity Vector Exploitability Impact Score source
6.7 3.1 MEDIUM
CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:H)
They need powerful rights—admin, root, or similar—before this pays off.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
