How to Fix CVE-2026-24098

To remediate this vulnerability, upgrade all affected Apache airflow dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

apache-airflow fixed: 3.1.7 
pip install apache-airflow>=3.1.7
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show apache-airflow

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-24098, inspect your installed packages using pip:

pip show apache-airflow

Analyze the terminal output to locate any version of Apache airflow in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.1.7), your application is affected.

Note: The pip show apache-airflow command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Apache airflow, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact **Exposure of Sensitive Information:** An information disclosure vulnerability exists in the Apache Airflow UI that allows authenticated users to view `Import Errors` for DAGs they are not authorized to access. In affected versions, the **Import Errors** view does not correctly filter errors based on granular DAG permissions. This means a user with access to only `DAG_A` can view import errors generated by `DAG_B`, `DAG_C`, or system-level DAGs. These error logs often contain file paths, code snippets, or stack traces that reveal the internal structure and logic of restricted DAGs. ### Patches Users should upgrade to Apache Airflow **3.1.7** or later. This version strictly enforces DAG-level permissions on the Import Errors view. ### Workarounds There are no known workarounds other than upgrading. ### Resources * [CVE-2026-24098](https://nvd.nist.gov/vuln/detail/CVE-2026-24098) * [Pull Request #60801](https://github.com/apache/airflow/pull/60801) * [Mailing List Announcement](https://lists.apache.org/thread/nx96435v77xdst7ls5lk57kqvqyj095x)
