# CVE-2026-119084 - Remote Code Execution via Unsafe Class Loading in Amazon Redshift JDBC Driver Connection Parameters

Versions of the Amazon Redshift JDBC driver before 2.3.0 can load and execute arbitrary classes when processing JDBC connection URL parameters or AWS credentials profile fields. An attacker who can influence the connection URL or credentials profile could execute code in the application's context.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the driver version in your build file or dependency tree (for example, the Redshift JDBC artifact in Maven Central) and see whether it is below `2.3.0`
- Review where your application builds JDBC connection URLs and AWS credentials profiles, and whether any part comes from untrusted input

## Fix

- Amazon Redshift JDBC Driver: upgrade to `2.3.0` or later, per the AWS bulletin, and patch any forked or derivative code

### CVE-2026-119084 - Remote Code Execution via Unsafe Class Loading in Amazon Redshift JDBC Driver Connection Parameters

Bulletin ID: 2026-168-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 11/03/2026 13:00 PM PST

Description:

Amazon Redshift JDBC Driver is a Type 4 JDBC driver that provides database connectivity through the standard JDBC application program interfaces (APIs). We identified CVE-2026-119084, an issue in Amazon Redshift JDBC Driver versions prior to 2.3.0. Under certain conditions, the driver could load and execute arbitrary classes when processing JDBC connection URL parameters or AWS credentials profile fields. An actor who can influence the connection URL or credentials profile could potentially execute code in the application context.

Impacted versions: Amazon Redshift JDBC Driver < 2.3.0

Resolution:

This issue has been addressed in Amazon Redshift JDBC Driver version 2.3.0. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes. The latest driver is available from the Amazon Redshift documentation and Maven Central.

Workarounds:

If you cannot upgrade immediately, review how your application builds JDBC connection URLs and AWS credentials profiles. Do not build them from untrusted input, or validate any externally supplied values against an allowlist of expected parameters and values.
