Amazon Redshift JDBC Driver 2.3.0: Unsafe Reflection in URL/Profile Allow RCE
CVE-2026-119084 Published on November 3, 2026

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

Weakness Type

What is a Reflection Injection Vulnerability?

The application uses external input with reflection to select which classes or code to use, but it does not sufficiently prevent the input from selecting improper classes or code. If the application uses external inputs to determine which class to instantiate or which method to invoke, then an attacker could supply values to select unexpected classes or methods. If this occurs, then the attacker could create control flow paths that were not intended by the developer. These paths could bypass authentication or access control checks, or otherwise cause the application to behave in an unexpected manner. This situation becomes a doomsday scenario if the attacker can upload files into a location that appears on the application's classpath (CWE-427) or add new entries to the application's classpath (CWE-426). Under either of these conditions, the attacker can use reflection to introduce new, malicious behavior into the application.

CVE-2026-119084 has been classified to as a Reflection Injection vulnerability or weakness.
