How to Fix CVE-2023-31580

To remediate this vulnerability, upgrade all affected Light oauth2 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

com.networknt:light-oauth2 fixed: 2.1.27 
<dependency>
    <groupId>com.networknt</groupId>
    <artifactId>light-oauth2</artifactId>
    <version>2.1.27</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=com.networknt

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-31580, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.networknt

Analyze the terminal output to locate any version of Light oauth2 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.1.27), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.networknt 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-295: Improper Certificate Validation, where the product does not validate, or incorrectly validates, a certificate. In Light oauth2, 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

light-oauth2 before version 2.1.27 obtains the public key without any verification. This could allow attackers to authenticate to the application with a crafted JWT token.
