How to Fix CVE-2019-3802

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

org.springframework.data:spring-data-jpa fixed: 2.1.8 
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
    <version>2.1.8</version>
</dependency>
org.springframework.data:spring-data-jpa fixed: 2.1.8 
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
    <version>2.1.8</version>
</dependency>
org.springframework.data:spring-data-jpa fixed: 1.11.22 
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
    <version>1.11.22</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=org.springframework.data

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2019-3802, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.springframework.data

Analyze the terminal output to locate any version of Spring Framework in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.1.8), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.springframework.data 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-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Spring Framework, 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

This affects Spring Data JPA in versions up to and including 2.1.6, 2.0.14 and 1.11.20. ExampleMatcher using ExampleMatcher.StringMatcher.STARTING, ExampleMatcher.StringMatcher.ENDING or ExampleMatcher.StringMatcher.CONTAINING could return more results than anticipated when a maliciously crafted example value is supplied.
