CVE-2026-8178 Amazon CVE debrief
A critical vulnerability exists in Amazon Redshift JDBC Driver versions prior to 2.2.2. The driver could load and execute arbitrary classes when processing JDBC connection URL parameters, potentially allowing code execution in the application context. Users should upgrade to version 2.2.2 or later to mitigate this issue. This issue is particularly concerning as it could allow an actor with influence over the connection URL to execute code, provided a suitable class is available on the application's classpath. Defenders and administrators should assess exposure and prioritize upgrading to version 2.2.2 or later. The vulnerability's impact is heightened by its potential for arbitrary
