Missing authorization checks in Amazon Athena engine version 3 request handling could have allowed an authenticated user to read limited query metadata (AWS account identifiers and SQL statement text) from other AWS accounts. Query results, credentials, and Amazon S3 data were not affected. AWS remediated the issue on September 1, 2026, and has confirmed no customer metadata was accessed. No customer action is required.
