CVE-2026-26929 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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.. EPSS estimates a 0.41% chance of exploitation in the next 30 days.
