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.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 6.8, indicating it can be exploited remotely over the network with relatively low complexity without requiring user interaction . The vulnerability impacts confidentiality (data exposure), for affected systems.
Reported in 2026, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For affected software, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
