CVE-2026-24098 — Apache Airflow: Assigning single DAG permission leaked all DAGs Import Errors

Affected: Apache Software Foundation Apache Airflow

Apache Airflow versions 3.0.0 - 3.1.7, has vulnerability that allows authenticated UI users with permission to one or more specific Dags to view import errors generated by other Dags they did not have access to.

Users are advised to upgrade to 3.1.7 or later, which resolves this issue

GHSA-5g2w-9f8g-g5q7 — Apache Airflow UI Exposes DAG Import Errors to Unauthorized Authenticated Users

Affected: PyPI: apache-airflow

### 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.
