How to Fix GHSA-94g8-xv23-7656
To remediate this vulnerability, upgrade all affected Vaadin upload flow dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-upload-flow</artifactId>
<version>14.13.1</version>
</dependency><dependency>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-upload-flow</artifactId>
<version>23.6.2</version>
</dependency><dependency>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-upload-flow</artifactId>
<version>24.7.7</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=com.vaadinHow to Check if You Are Affected
To determine whether your Java application is affected by GHSA-94g8-xv23-7656, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=com.vaadinAnalyze the terminal output to locate any version of Vaadin upload flow 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.
