How to Fix GHSA-c7v7-rqfm-f44j

To remediate this vulnerability, upgrade all affected Vaadin 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 fixed: 14.13.1 
<dependency>
    <groupId>com.vaadin</groupId>
    <artifactId>vaadin</artifactId>
    <version>14.13.1</version>
</dependency>
com.vaadin:vaadin fixed: 23.6.2 
<dependency>
    <groupId>com.vaadin</groupId>
    <artifactId>vaadin</artifactId>
    <version>23.6.2</version>
</dependency>
com.vaadin:vaadin fixed: 24.7.7 
<dependency>
    <groupId>com.vaadin</groupId>
    <artifactId>vaadin</artifactId>
    <version>24.7.7</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-c7v7-rqfm-f44j, 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 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 14.13.1), 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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Vaadin, 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

### Description When the Vaadin Upload's start listener is used to validate metadata about an incoming upload, it is possible to bypass the upload validation. Users of affected versions should apply the upgrade to a more recent Vaadin version.
