How to Fix CVE-2022-23945

To remediate this vulnerability, upgrade all affected Shenyu common 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.apache.shenyu:shenyu-common fixed: 2.4.2 
<dependency>
    <groupId>org.apache.shenyu</groupId>
    <artifactId>shenyu-common</artifactId>
    <version>2.4.2</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.apache.shenyu

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-23945, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.apache.shenyu

Analyze the terminal output to locate any version of Shenyu common in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.4.2), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.shenyu 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.
