A SQL injection issue exists in the Hive Metastore Server (HMS) when handling delete column statistics requests through the Thrift APIs. This issue is exploitable only by authorized users or applications permitted to directly call the Thrift APIs. In typical deployments, HMS access is limited to a small number of applications, reducing the risk of exploitation. The vulnerable code is not reachable when the `metastore.try.direct.sql` property is set to false. The vulnerability involves processing requests via the following:
**API Endpoints**: Thrift APIs
**Vulnerable Parameters or Variables**: Requests to delete column statistics.
