Summary

Before Apache Airflow 3.3.0, a user authorized to read one DAG could disclose the source code of other DAGs co-located in the same source file. The `GET /api/v2/dagSources/{dag_id}` endpoint and the equivalent UI view returned the entire source file without redacting unauthorized DAGs, bypassing per-DAG read authorization.

Risk Assessment

Organizations that co-locate multiple DAGs in a single file and rely on per-DAG access control to limit source visibility are at risk of leaking sensitive workflow definitions to unauthorized users.

Recommendation

Upgrade Apache Airflow to version 3.3.0 or later immediately. As a temporary workaround, consider separating DAGs into individual files (one DAG per file).

Original NVD description (English source)

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.
