Description
Input Validation vulnerability in Apache Software Foundation Apache Airflow ODBC Provider, Apache Software Foundation Apache Airflow MSSQL Provider.This vulnerability is considered low since it requires DAG code to use get_sqlalchemy_connection and someone with access to connection resources specifically updating the connection to exploit it.
This issue affects Apache Airflow ODBC Provider: before 4.0.0; Apache Airflow MSSQL Provider: before 3.4.1.
It is recommended to upgrade to a version that is not affected

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-odbc. 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-odbc to 4.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-35798 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 CVE-2023-35798 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 CVE-2023-35798. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
