CVE-2026-49487: CWE-200: Exposure of Sensitive Information to an Unauthorized Actor in Apache Software Foundation Apache Airflow
Apache Airflow versions prior to 3.3.0 have a vulnerability where the REST API task-instance detail and list endpoints expose sensitive information in trigger kwargs without masking. This allows any authenticated user with DAG-scoped task-instance read access to view secrets such as provider API keys in clear text when a deferred operator passes them into its trigger. The issue is fixed in version 3.3.0 by masking sensitive values in the API responses.
AI Analysis
Technical Summary
In Apache Airflow before version 3.3.0, the REST API endpoints for task-instance details and lists returned trigger kwargs of deferred tasks without masking sensitive data. This flaw allows authenticated users with read access scoped to a DAG to retrieve secrets (e.g., API keys) passed into deferred operators in clear text. The vulnerability is categorized as CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). Upgrading to Apache Airflow 3.3.0 or later mitigates this issue by masking sensitive values in the trigger kwargs returned by the API.
Potential Impact
Authenticated users with DAG-scoped task-instance read access can access sensitive secrets in clear text via the REST API when tasks are deferred and pass secrets in their triggers. This exposure could lead to unauthorized disclosure of confidential information such as API keys, potentially compromising integrations or services relying on those secrets.
Mitigation Recommendations
Upgrade Apache Airflow to version 3.3.0 or later, where the issue is fixed by masking sensitive values in trigger kwargs returned by the REST API. No other official remediation or temporary fixes are indicated. Patch status is not explicitly confirmed in the vendor advisory, but the upgrade to 3.3.0 is the recommended fix.
