Authorization Bypass Through User-Controlled Key

Overview Affected versions of this package are vulnerable to Authorization Bypass Through User-Controlled Key via the GET /api/v2/dagSources/dagid endpoint, which returns the entire source file containing multiple DAGs without redacting those the user is not authorized to access. An attacker can...

PYSEC-2026-1150 Apache Airflow ODBC Provider, Apache Airflow MSSQL Provider Improper Input Validation vulnerability

Input Validation vulnerability in Apache Software Foundation Apache Airflow ODBC Provider, Apache Software Foundation Apache Airflow MSSQL Provider.This vulnerability is considered low since it requires DAG code to use getsqlalchemyconnection and someone with access to connection resources...

CVE-2026-49296

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/dagid — and the equivalent Dag-source view in the UI — returned the entire source file without redacting Dags the caller was not...

CVE-2026-48891

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. An authenticated UI user with...

CVE-2026-33264

A bug in BaseSerialization.deserialize allowed unrestricted importstring of attacker-controlled class paths when the Scheduler / API Server loaded a serialized DAG: a DAG author could embed a malicious trigger into a DAG to gain remote code execution on the API Server / Scheduler process, crossin...

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-2026-49296

CVE-2026-49296 (Apache Airflow) : Affected versions before 3.3.0 expose the full source of co-located DAGs when reading a single DAG via GET /api/v2/dagSources/{dag_id} or the UI view, bypassing per-DAG read controls. This can disclose multiple DAG sources from the same file to authorized readers...

CVE-2026-49296 Apache Airflow: Per-DAG read bypass discloses co-located DAGs' source via GET /api/v2/dagSources/{dag_id}
