Specifically, versions prior to 2.1.0.0 are susceptible to unbounded resource allocation within their parsing components. An unauthenticated, remote attacker can exploit this weakness by sending specially crafted input to a system utilizing the vulnerable driver, leading to excessive resource consumption during parsing. This results in a denial of service condition, potentially impacting availability of applications relying on the Athena ODBC driver. The vulnerability was publicly disclosed on April 3, 2026, and defenders should prioritize upgrading to version 2.1.0.0 or later.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker identifies a system utilizing a vulnerable version of the Amazon Athena ODBC driver (versions prior to 2.1.0.0).\u003c/li\u003e\n\u003cli\u003eThe attacker crafts malicious input designed to trigger excessive resource consumption in the driver\u0026rsquo;s parsing component.\u003c/li\u003e\n\u003cli\u003eThe attacker sends the crafted input to the target system via a network connection.
