CVE-2026-49487 Apache Airflow: Task-instance API exposes secrets in deferred trigger kwargs

In Apache Airflow before 3.3.0, the REST API task-instance detail and list endpoints returned a deferred task's trigger kwargs without masking. When a deferred operator passed a secret for example a provider API key into its trigger, any authenticated user with DAG-scoped task-instance read acces...

CVE-2026-48891

A vulnerability in Apache Airflow affects the UI at /ui/dependencies where the scheduling graph endpoint applies the caller’s readable-Dag filter to the top-level Dag key but still exposes Dag IDs in dep.source and dep.target for trigger/sensor entries. An authenticated UI user with read access t...

EUVD-2026-42025

A bug in Apache Airflow's /ui/dependencies scheduling graph endpoint applied the caller's readable-Dag filter to the top-level serialized Dag key but still emitted referenced Dag IDs through the dep.source and dep.target fields of trigger / sensor dependency entries.

CVE-2026-40963

The CVE-2026-40963 issue affects the Apache Airflow UI’s /ui/structure/structure_data endpoint. It allows an authenticated user with access to one Dag to enumerate dependency graph nodes and related metadata for other Dags for which they lack read permissions, leaking topology across teams when p...

CVE-2026-41014 Apache Airflow: per-DAG RBAC bypass on /ui/partitioned_dag_runs endpoints

The partitioneddagruns endpoints in the Airflow UI enforced only asset-level access control, not per-Dag authorization. An authenticated UI/API user with global Asset:read permission could enumerate partition run state, schedule configuration, and asset wiring for Dags they were not authorized to...

CVE-2026-40690

The asset dependency graph did not restrict nodes by the viewer's DAG read permissions: a user with read access to at least one DAG could browse the asset graph for any other asset in the deployment and learn the existence and names of DAGs and assets outside their authorized scope. Users are...
