CVE-2025-66236: CWE-532: Insertion of Sensitive Information into Log File in Apache Software Foundation Apache Airflow
Before Airflow 3.2.0, it was unclear that secure Airflow deployments require the Deployment Manager to take appropriate actions and pay attention to security details and security model of Airflow. Some assumptions the Deployment Manager could make were not clear or explicit enough, even though Airflow's intentions and security model of Airflow did not suggest different assumptions. The overall security model [1], workload isolation [2], and JWT authentication details [3] are now described in more detail. Users concerned with role isolation and following the Airflow security model of Airflow are advised to upgrade to Airflow 3.2, where several security improvements have been implemented. They should also read and follow the relevant documents to make sure that their deployment is secure enough. It also clarifies that the Deployment Manager is ultimately responsible for securing your Airflow deployment. This had also been communicated via Airflow 3.2.0 Blog announcement [4]. [1] Security Model: https://airflow.apache.org/docs/apache-airflow/stable/security/jwt_token_authentication.html [2] Workload isolation: https://airflow.apache.org/docs/apache-airflow/stable/security/workload.html [3] JWT Token authentication: https://airflow.apache.org/docs/apache-airflow/stable/security/jwt_token_authentication.html [4] Airflow 3.2.0 Blog announcement: https://airflow.apache.org/blog/airflow-3.2.0/ Users are recommended to upgrade to version 3.2.0, which fixes this issue.
AI Analysis
Technical Summary
This vulnerability (CVE-2025-66236) in Apache Airflow prior to version 3.2.0 involves the insertion of sensitive information into log files due to unclear deployment assumptions and insufficient guidance on Airflow's security model. The issue is categorized under CWE-532, indicating sensitive data exposure through logging. The Apache Software Foundation has improved the security model, workload isolation, and JWT authentication in Airflow 3.2.0, which also includes clarifications emphasizing the Deployment Manager's responsibility for securing the deployment. Users are recommended to upgrade to version 3.2.0 to mitigate this vulnerability.
Potential Impact
The vulnerability can lead to the exposure of sensitive information in log files if the deployment is not properly secured according to Airflow's security model. This could result in unauthorized disclosure of sensitive data. The CVSS score of 7.5 (high severity) reflects the potential impact on confidentiality, with no impact on integrity or availability. There are no known exploits in the wild at this time.
Mitigation Recommendations
Users should upgrade to Apache Airflow version 3.2.0, which includes security improvements and clarifications addressing this vulnerability. The vendor advisory emphasizes that the Deployment Manager is ultimately responsible for securing Airflow deployments and should follow the updated security documentation on workload isolation and JWT authentication. Patch status is not explicitly stated, but upgrading to 3.2.0 is the recommended remediation.
