CVE-2026-119084 PUBLISHED

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

Assigner: AMZN
Reserved: 29.10.2026 Published: 03.11.2026 Updated: 03.11.2026

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.
