Apache Airflow UI Exposes DAG Import Errors to Unauthorized Authenticated Users

Moderate severity GitHub Reviewed Published Feb 9, 2026 to the GitHub Advisory Database • Updated Feb 11, 2026

Package

pip apache-airflow (pip)

Affected versions

< 3.1.7

Patched versions

3.1.7

Description

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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
