AI-suggested

Upgrade awswrangler to version 3.16.1 or later, where this vulnerability has been addressed. Users should ensure that the default Athena query result location is not set to an S3 bucket they do not fully control or verify ownership of. Follow the AWS Security Bulletin for the latest remediation guidance.

Description

CVE-2026-118029 affects the AWS SDK for pandas (awswrangler) Athena module. The vulnerability involves unverified ownership of the default Athena query result location, which could allow a remote user to read query results and tamper with them if a pre-created S3 bucket is used. Versions of awswrangler prior to 3.16.1 are impacted. AWS has published a security bulletin advising attention to this issue.
