Description
Incorrect authorization checks in Amazon Athena engine version 3 query processing could have allowed an authenticated user to read AWS account identifiers and SQL statement text query metadata from other AWS accounts. Query results, and data stored in Amazon S3 or other data sources, were not accessible through this issue. AWS remediated the issue on October 7, 2026. No customer action is required.
