How to Fix GHSA-j9wr-49vq-rm5g

To remediate this vulnerability, upgrade all affected Vaadin bom 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.vaadin:vaadin-bom fixed: 14.4.10 
<dependency>
    <groupId>com.vaadin</groupId>
    <artifactId>vaadin-bom</artifactId>
    <version>14.4.10</version>
</dependency>
com.vaadin:vaadin-bom fixed: 19.0.1 
<dependency>
    <groupId>com.vaadin</groupId>
    <artifactId>vaadin-bom</artifactId>
    <version>19.0.1</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.vaadin

How to Check if You Are Affected

To determine whether your Java application is affected by GHSA-j9wr-49vq-rm5g, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.vaadin

Analyze the terminal output to locate any version of Vaadin bom in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 14.4.10), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.vaadin 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-402: Transmission of Private Resources into a New Sphere ('Resource Leak'), where the product makes resources available to untrusted parties when those resources are only intended to be accessed by the product. In Vaadin bom, 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

Vulnerability in OSGi integration in `com.vaadin:flow-server` versions 1.2.0 through 2.4.7 (Vaadin 12.0.0 through 14.4.9), and 6.0.0 through 6.0.1 (Vaadin 19.0.0) allows attacker to access application classes and resources on the server via crafted HTTP request. - https://vaadin.com/security/cve-2021-31407
