A missing authorization vulnerability was found in the Event-Driven Ansible (EDA) websocket API. The /api/eda/ws/ansible-rulebook endpoint does not verify user permissions when processing Worker messages. Any authenticated user can send a forged message with an arbitrary activation_id to receive plaintext credentials associated with that activation, including OAuth tokens, vault passwords, and SSH keys.
Security readout for executives and security teams
Plain-English summary
This flaw lets any authenticated Ansible Automation Platform user abuse the EDA websocket API to obtain plaintext credentials tied to another activation. Exposed secrets may include OAuth tokens, vault passwords, and SSH keys, so the business risk is credential theft and downstream compromise of automated infrastructure.
Executive priority
Treat as urgent because a normal authenticated user could obtain automation secrets that unlock broader systems. Patch affected AAP EDA deployments, reduce access, and rotate exposed credentials where misuse cannot be ruled out.
Technical view
CVE-2026-11807 is CWE-862 missing authorization in Event-Driven Ansible. The /api/eda/ws/ansible-rulebook endpoint processes Worker messages without verifying permissions, allowing an authenticated user to spoof an activation_id and receive credentials associated with that activation. CVSS is 9.6, with low attack complexity and low privileges required.
Likely exposure
Exposure is likely where Red Hat Ansible Automation Platform 2.5, 2.6, or 2.7 includes affected EDA controller packages or images and untrusted or compromised authenticated accounts exist. Risk is highest when EDA activations hold privileged automation credentials.
Exploitation context
The source bundle does not show CISA KEV listing or confirmed active exploitation. The documented path requires authentication, but not elevated permissions, and directly exposes high-value credentials through an authorization failure.
Researcher notes
Evidence is strongest for Red Hat AAP EDA controller versions listed in the bundle. Do not generalize beyond those products. The bundle names vendor advisories but does not include detailed fixed-version text, so use Red Hat guidance for final package mapping.
Mitigation direction
Apply the relevant Red Hat RHSA updates for affected Ansible Automation Platform EDA controller deployments.
Restrict authenticated access to EDA features until vendor fixes are applied.
Rotate OAuth tokens, vault passwords, and SSH keys tied to exposed or suspicious activations.
Review Red Hat advisories for exact fixed packages, images, and deployment-specific instructions.
Prioritize environments where EDA credentials can administer production infrastructure.
Validation and detection
Inventory Ansible Automation Platform 2.5, 2.6, and 2.7 deployments using EDA controller.
Compare installed automation-eda-controller packages and images against the affected versions in Red Hat data.
Confirm applicable RHSA updates are installed across RHEL 8, RHEL 9, and container deployments.
Review EDA/websocket audit logs for unusual authenticated access involving ansible-rulebook or activation IDs.
Verify only authorized users can access credentials associated with EDA activations after remediation.

CWE-862: Authorization and privilege behavior lookup
Authorization weaknesses can support privilege escalation and valid-account review, depending on exploit path. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references authentication or credential exposure, so valid-account and credential-access review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Missing Authorization
Missing Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
