How to Fix GHSA-7xw4-g7mm-r4hh

To remediate this vulnerability, upgrade all affected Aws advanced jdbc wrapper dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

software.amazon.jdbc:aws-advanced-jdbc-wrapper fixed: 2.6.5 
<dependency>
    <groupId>software.amazon.jdbc</groupId>
    <artifactId>aws-advanced-jdbc-wrapper</artifactId>
    <version>2.6.5</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=software.amazon.jdbc

How to Check if You Are Affected

To determine whether your Java application is affected by GHSA-7xw4-g7mm-r4hh, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=software.amazon.jdbc

Analyze the terminal output to locate any version of Aws advanced jdbc wrapper in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.6.5), your application is affected.

Note: The mvn dependency:tree -Dincludes=software.amazon.jdbc command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-470: Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection'), where the product 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. In Aws advanced jdbc wrapper, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Description of Vulnerability: An issue in AWS Wrappers for Amazon Aurora PostgreSQL may allow for privilege escalation to rds_superuser role. A low privilege authenticated user can create a crafted function that could be executed with permissions of other Amazon Relational Database Service (RDS) users. AWS recommends for customers to upgrade to the following versions: AWS JDBC Wrapper to v2.6.5 or greater. ### Source of Vulnerability Report: Allistair Ishmael Hakim [allistair.hakim@gmail.com](mailto:allistair.hakim@gmail.com) ### Affected products & versions: AWS JDBC Wrapper < 2.6.5 ### Platforms: MacOS/Windows/Linux
