Unverified ownership of the default query result location in the Athena module in AWS SDK for pandas (awswrangler) before 3.16.1 might allow remote actors to read Athena query results and tamper with result sets returned to the caller via a pre-created S3 bucket. To remediate this issue, users should upgrade to version 3.16.1 or later. Users should also verify that the default Athena result bucket in each account and region is owned by their own account, and set an explicit result location or enforce a workgroup result configuration.
