CVE-2026-8178 - Remote Code Execution via Unsafe Class Loading in Amazon Redshift JDBC Driver
Published May 8, 2026 · corrected/updated Jun 17, 2026 · Amazon Web Services · evidence confidence high
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.
