Doc Text:
A flaw was found in AWS SDK for pandas (awswrangler). The Athena module does not verify the ownership of the default query result location in Amazon Simple Storage Service (S3). A remote attacker who pre-creates the default S3 storage bucket can exploit this vulnerability to read sensitive Athena query results and tamper with data returned to the user.

Description OSIDB Bzimport 2026-10-28 15:43:29 UTC
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.
