How to Fix CVE-2022-31139

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

io.github.karlatemp:unsafe-accessor fixed: 1.7.0 
<dependency>
    <groupId>io.github.karlatemp</groupId>
    <artifactId>unsafe-accessor</artifactId>
    <version>1.7.0</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=io.github.karlatemp

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-31139, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.github.karlatemp

Analyze the terminal output to locate any version of Unsafe accessor in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.7.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=io.github.karlatemp 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 Unsafe accessor, 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

### Overview Affected versions have no limit to using unsafe-accessor. Can be ignored if `SecurityCheck.AccessLimiter` not setup ### Details If UA was loaded as a named module, the internal data of UA will be protected by JVM and others can only access UA via UA's standard api. Main application can setup `SecurityCheck.AccessLimiter` for UA to limit accesses to UA. Untrusted code can access UA without lmitation in affected versions even UA was loaded as a named module. ### References [The commit to fix](https://github.com/Karlatemp/UnsafeAccessor/commit/4ef83000184e8f13239a1ea2847ee401d81585fd)
