CVE-2026-24098: Apache Airflow: Assigning single DAG permission leaked all DAGs Import Errors
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 DAGA can view import errors generated by DAGB, DAGC, 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.
