Title

Remote Code Execution via Unsafe Class Loading in Amazon Redshift JDBC Driver

Summary

An issue exists in Amazon Redshift JDBC Driver versions prior to 2.2.2. Under certain conditions, the driver could load and execute arbitrary classes when processing JDBC connection URL parameters. An actor who can influence the connection URL could potentially execute code in the application context, provided a suitable class is available on the application's classpath. To mitigate this issue, users should upgrade to version 2.2.2 or later.

Vulnerability from github – Published: 2026-05-14 13:09 – Updated: 2026-05-14 13:09

Summary

Amazon Redshift Vulnerable to Remote Code Execution via Unsafe Class Loading

Details

Summary

Amazon Redshift JDBC Driver is a Type 4 JDBC driver that provides database connectivity through the standard JDBC application program interfaces (APIs). An issue exists in versions prior to 2.2.2 where the driver could load arbitrary classes when processing certain connection URL parameters, potentially allowing code execution in the application context.

Impact

When a JDBC connection URL contains certain parameters, the driver processes the parameter values in a way that could trigger the execution of code from classes available on the application's classpath. An actor who can influence the JDBC connection URL could leverage this to execute code in the context of the application's JVM process. Successful exploitation could allow the actor to read sensitive data, modify application state, or disrupt service availability with the privileges of the application process.

Impacted versions: Amazon Redshift JDBC Driver < 2.2.2

Patches

This issue has been addressed in Amazon Redshift JDBC Driver version 2.2.2. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes.
