CVE-2026-118029— Unverified ownership of the default Athena query result location in AWS SDK for pandas

Quick assessment

Affected
aws aws-sdk-pandas
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 AWS SDK for pandas（awswrangler）的 Athena 模块中，3.16.1 版本之前未对默认查询结果存储位置的所有权进行验证。这可能导致远程攻击者读取 Athena 查询结果，并通过预先创建的 S3 存储桶篡改返回给调用方的结果集。 为修复此问题，用户应升级至 3.16.1 或更高版本。此外，用户还需验证每个账户和区域中的默认 Athena 结果存储桶是否由自身账户拥有，并显式指定结果存储位置，或配置工作组（workgroup）的结果存储策略以强制指定位置。

Vulnerability Title
Unverified ownership of the default Athena query result location in AWS SDK for pandas
Source: CVE Program / CVE List V5
Vulnerability Description
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.
