## Overview

### 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.
