How to Fix CVE-2022-0671

To remediate this vulnerability, upgrade all affected Lemminx parent 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.eclipse.lemminx:lemminx-parent fixed: 0.19.0 
<dependency>
    <groupId>org.eclipse.lemminx</groupId>
    <artifactId>lemminx-parent</artifactId>
    <version>0.19.0</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=org.eclipse.lemminx

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-0671, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.eclipse.lemminx

Analyze the terminal output to locate any version of Lemminx parent in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.19.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.eclipse.lemminx 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource.
