Path Traversal in apache-airflow-providers-google (CVE-2026-49297)
Summary
Path traversal in apache-airflow-providers-google (CVE-2026-49297). Data can be tampered with by attackers. Exploitable via GCSToSFTPOperator. Mitigation: upgrade to 22.2.1 or later.
Original description
The description as published by the source.
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.
