Description

Summary

Amazon Redshift JDBC Driver is a Type 4 JDBC driver that provides database connectivity through the standard JDBC application program interfaces (APIs). An issue exists in versions prior to 2.2.2 where the driver could load arbitrary classes when processing certain connection URL parameters, potentially allowing code execution in the application context.

Impact

When a JDBC connection URL contains certain parameters, the driver processes the parameter values in a way that could trigger the execution of code from classes available on the application's classpath. An actor who can influence the JDBC connection URL could leverage this to execute code in the context of the application's JVM process. Successful exploitation could allow the actor to read sensitive data, modify application state, or disrupt service availability with the privileges of the application process.

Impacted versions: Amazon Redshift JDBC Driver < 2.2.2

Patches

This issue has been addressed in Amazon Redshift JDBC Driver version 2.2.2. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.amazon.redshift:redshift-jdbc42, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update com.amazon.redshift:redshift-jdbc42 to 2.2.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-wmmv-vvg5-993q is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
