CVE-2026-26929

MEDIUM

Apache Airflow: Wildcard DagVersion Listing Bypasses Per‑DAG RBAC and Leaks Metadata

Title source: cna

Description

Apache Airflow versions 3.0.0 through 3.1.7 FastAPI DagVersion listing API does not apply per-DAG authorization filtering when the request is made with dag_id set to "~" (wildcard for all DAGs). As a result, version metadata of DAGs that the requester is not authorized to access is returned. Users are recommended to upgrade to Apache Airflow 3.1.8 or later, which resolves this issue.
