apache-airflow DAG source authorization bypass exposes co-located DAG source

Apache Airflow

CVE-2026-49296 · Published Jul 7, 2026 · updated Aug 12, 2026

Medium6.5
Fix: upgrade to 3.3.0 or later
GitHub advisory

Before apache-airflow 3.3.0, a user authorized to read one Dag could disclose the source of other Dags co-located in the same source file. GET /api/v2/dagSources/{dag_id} , and the equivalent Dag-source view in the UI , returned the entire source file without redacting Dags the caller was not authorized to read, bypassing per-DAG read authorization. Deployments that co-locate multiple Dags in a single file and rely on per-DAG access control to limit source visibility are affected; single-Dag-per-file deployments are not. Upgrade to apache-airflow 3.3.0 or later.
