Background
Apache Airflow is an open-source platform designed to programmatically author, schedule, and monitor workflows. It allows users to define workflows as Directed Acyclic Graphs (DAGs) and provides a rich user interface to manage and visualize these workflows. However, due to its extensive use of parameters (kwargs) in operators, it can inadvertently expose sensitive information if not properly managed.
Vulnerability Detail
The vulnerability arises when a Directed Acyclic Graph (DAG) fails during parsing. In such cases, Apache Airflow's error reporting mechanism in the user interface may display the complete kwargs passed to the operators. If these kwargs contain sensitive information, such as secrets or credentials, they can be exposed to authenticated users who have permission to view that specific DAG. This could lead to unauthorized access to sensitive data, making it a significant security concern.
How To Fix
Latest published version: 3.3.2 as of 22 Oct 2026
pip install --upgrade "apache-airflow==3.3.2"Upgrading to it may include breaking changes; the versions below are the minimum fixed release for this vulnerability.

Workaround
As a temporary measure, users can avoid including sensitive information in the kwargs passed to operators until they can upgrade to the patched versions. Additionally, consider restricting access to the Airflow UI to limit exposure to authenticated users.
Conclusion
In summary, CVE-2025-65995 is a moderate severity vulnerability in Apache Airflow that can expose sensitive information through error reporting. Users are strongly advised to upgrade to the latest patched versions to mitigate this risk and ensure the security of their workflows.
