Amazon Athena is a serverless, interactive query service that lets you analyze data directly in Amazon S3 using standard SQL. Athena Query Federation is a feature that allows you to connect to data sources outside of Amazon S3 like DynamoDB, Azure Synapse, and custom connectors using standard SQL syntax. Improper neutralization of special elements used in an SQL command in the Synapse connector in Amazon aws-athena-query-federation v2022.20.1 through v2026.19.1 might allow an authenticated remote user to execute injected read-only SQL queries that return unintended data from the connected database via a crafted table name.
To remediate this issue, users should upgrade to version v2026.21.1 or later.
