GHSA-f6vj-48fm-hmvx
MEDIUMGHSA-f6vj-48fm-hmvx is a medium-severity (CVSS 6.5) Path Traversal vulnerability in apache-airflow-providers-samba. O3 Security confirms whether GHSA-f6vj-48fm-hmvx is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for apache-airflow-providers-samba. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
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
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-f6vj-48fm-hmvx is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-f6vj-48fm-hmvx. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-f6vj-48fm-hmvx in your dependencies?
O3 detects GHSA-f6vj-48fm-hmvx across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
