Go to dashboardAWS SDK for pandas (awswrangler) trusts the default Athena query result S3 location without checking who owns it. A remote user who pre-creates that bucket can read Athena query results and tamper with the result sets returned to the caller.

Teams running awswrangler below 3.16.1 that use Athena through the library and rely on the default query result location. Exposure depends on whether the default result bucket in the account and Region could be pre-created by someone else. Teams with an explicit result location or an enforced workgroup result configuration, or who run only newer versions, can skip it.

CVE-2026-118029 - Unverified ownership of the default Athena query result location in AWS SDK for pandas
Bulletin ID: 2026-153-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 10/28/2026 08:30 AM PDT
Description:
AWS SDK for pandas (awswrangler) is an open-source Python library that integrates pandas with AWS data services such as Amazon Athena, Amazon S3, and AWS Glue. We identified CVE-2026-118029 in the Athena module, where unverified ownership of the default query result location could allow a remote user to read Athena query results and tamper with result sets returned to the caller via a pre-created S3 bucket.
Impacted versions: awswrangler < 3.16.1
Resolution:
This issue has been addressed in AWS SDK for pandas version 3.16.1, released May 8, 2026. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes.
Workarounds:
Verify that the default Athena result bucket in each account and Region is owned by your own account, and set an explicit result location or enforce a workgroup result configuration.
