Apache Airflow: Authenticated users can bypass the `is_safe_url` check

A bug in the login redirect route in Apache Airflow allowed authenticated users to craft URLs that bypassed the issafeurl check, enabling redirection from a trusted Airflow domain to an attacker-controlled origin. Users are advised to upgrade to apache-airflow 3.2.2 or later. As a defense-in-dept...

Apache Airflow vulnerable to Code Injection in the web-server context via LogTemplate table

DAG Author who already has quite a lot of permissions could manipulate database of Airflow 2 in the way to execute arbitrary code in the web-server context, which they should normally not be able to do, leading to potentially remote code execution in the context of web-server server-side as a...

Apache Airflow has a command injection vulnerability in "example_dag_decorator"

An example dag exampledagdecorator had non-validated parameter that allowed the UI user to redirect the example to a malicious server and execute code on worker. This however required that the example dags are enabled in production not default or the example dag code copied to build your own...

CVE-2026-49487

Apache Airflow versions before 3.3.0 are vulnerable to information disclosure via the REST API task-instance detail and list endpoints . The root cause is that these endpoints return a deferred task's trigger kwargs without masking. If a deferred operator includes a secret, such as a provider API...

CVE-2026-49486 Apache Airflow FTP provider: FTP Provider does not protect FTPS data channel (missing PROT_P)

The Apache Airflow FTP provider's FTPSHook.getconn created an ftplib.FTPTLS connection but never called protp, so although the control channel was TLS-protected the data channel was transmitted in cleartext. Any deployment using FTPSHook or FTPSFileTransmitOperator to move files over FTPS exposed...

CVE-2026-45192

A bug in the GET /api/v2/connections/connectionid REST API endpoint in Apache Airflow allowed an authenticated UI/API user with Connection-read permission to retrieve secrets stored in a Connection's extra JSON blob under field names not present in the redaction allowlist DEFAULTSENSITIVEFIELDS —...

BIT-AIRFLOW-2026-42360 Apache Airflow: Rendered template truncation bypasses nested sensitive-key masking

A bug in Apache Airflow's rendered-template field handling caused nested sensitive-key masking e.g. nested password / token / secret / apikey keys inside a JSON template structure to be bypassed when the rendered field exceeded core maxtemplatedfieldlength: Airflow stringified the structure befor...

CVE-2026-41014

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...

GHSA-5J6P-JRRM-6X94 Apache Airflow: Execution API JWT leaked via KubernetesExecutor worker command-line args

A bug in Apache Airflow's KubernetesExecutor caused JWT tokens used by worker pods to authenticate against the Execution API to be passed to the worker container as command-line arguments visible in the pod spec. An authenticated UI/API user with Kubernetes read-only access to the cluster e.g...
