Real-World Exposure
apache-airflow-providers-sambaReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
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 destination_path. 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 destination_path.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for apache-airflow-providers-samba, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update apache-airflow-providers-samba to 4.12.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-f6vj-48fm-hmvx is resolved across your whole dependency graph.
Workarounds
Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
