CVE-2024-27906Network attack vector

Authenticated DAG data disclosure via missing authorization

Published Feb 29, 2024 · Updated May 6, 2025

Missing authorization in Apache Airflow before 2.8.2 allows remote authenticated users to view restricted DAG code and import errors. The requires_access_dag decorator falls back to an any-DAG check for access_entity requests, while import-error handlers omit complete per-DAG checks. An account with access to one DAG can read source or error details belonging to DAGs outside its authorization scope through the UI or API.
