Apache Airflow has a Path Traversal issue
CVE-2026-49818 · GHSA-f6vj-48fm-hmvx
- Affected
- PyPI apache-airflow-providers-samba < 4.12.6
- Fixed in
- 4.12.6· Vendor fix available
- Issue
- The Apache Airflow Samba provider's GCSToSambaOperator joined GCS object names to the SMB destination path without a containment check, so an object named with ../ segments resolved a write path outside the configured destinationpath. An attacker able to write objects into the source GCS bucket — typically an external data producer distinct from the trusted DAG author — could write files to arbitrary locations on the Samba target when the operator ran. Upgrade apache-airflow-providers-samba to 4.12.6 or later, which validates the resolved destination stays within destinationpath.
Recommended action: Upgrade to 4.12.6 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
