Apache: >> Apache-Airflow-Providers-Google >> 1.3.1 Security Vulnerabilities
Apache Airflow's Google provider operators `GCSToSFTPOperator` and `GCSTimeSpanFileTransformOperator` joined GCS object names returned by the bucket listing API directly to a destination filesystem path without normalisation or containment check. A user with write access to the source GCS bucket (typically a different trust principal than the DAG author — partner uploads, ingest-only service accounts, public-data buckets) could create an object whose name contains `..` segments and cause the DAG run to write the downloaded blob outside the configured destination (the SFTP `destination_path` for `GCSToSFTPOperator`; the worker-local temp directory for `GCSTimeSpanFileTransformOperator`), enabling overwrite of arbitrary files on the SFTP server or the worker host. Affects deployments that ingest from buckets writable by less-trusted principals. Users are advised to upgrade to `apache-airflow-providers-google` 22.2.1 or later.

Apache Airflow providers-google's `ComputeEngineSSHHook` disables SSH host-key verification by default, exposing SSH traffic between an Airflow worker and a Compute Engine VM to in-path network attackers who can intercept or modify the session. Users are advised to upgrade to `apache-airflow-providers-google` 22.0.0 or later.
