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 are aware of CVE-2026-119301 in the Apache Iceberg write component, where improper neutralization of quoting syntax in SQL identifier construction could allow an authenticated user with permission to modify AWS Glue Data Catalog metadata to read any table that a separate, more privileged principal can access and write to the table that principal is updating via a crafted column name.

Impacted versions: awswrangler >= 3.5.2, < 3.17.1

Resolution:

This issue has been addressed in AWS SDK for pandas version 3.17.1, released August 3, 2026. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes.

Workarounds:

There is no complete workaround for earlier versions. Until you upgrade, avoid calling to_iceberg() with a principal that has more privileges than the principals who can modify that table's AWS Glue Data Catalog metadata, and restrict glue:UpdateTable and related permissions on shared databases.
