Severity: medium (CVSS 4.3 v3.1)
Exploited in the wild: not listed in CISA KEV
EPSS: 0.5% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2026-03-17 · updated 2026-06-17
Weakness: CWE-732

Description

Apache Airflow versions 3.1.0 through 3.1.7 /ui/dependencies endpoint returns the full DAG dependency graph without filtering by authorized DAG IDs. This allows an authenticated user with only DAG Dependencies permission to enumerate DAGs they are not authorized to view. Users are recommended to upgrade to Apache Airflow 3.1.8 or later, which resolves this issue.

Affected products

Apache Airflow: from 3.0.0 before 3.1.8 — fixed in 3.1.8

How to fix

Upgrade to a fixed version: Apache Airflow 3.1.8. Check the vendor advisory for mitigations.
