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 CVE-2026-7860, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.vaadin

Analyze the terminal output to locate any version of Flow plugins in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 23.6.11), 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-209: Generation of Error Message Containing Sensitive Information, where the product generates an error message that includes sensitive information about its environment, users, or associated data. In Flow plugins, 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

A possible information disclosure vulnerability exists in the Vaadin Maven plugin and Vaadin Gradle plugin that exposes the full set of environment variables in build logs whenever the frontend build process exits with a non-zero status. Because the build environment may contain credentials supplied as secrets, any failed frontend build can expose those secrets in clear text in CI logs and archived build artifacts. Users of affected versions should apply the following mitigation or upgrade. Releases that have fixed this issue include: | Product version | Mitigation | |---|---| | `Vaadin 23.0.0 - 23.6.10` | `Upgrade to 23.6.11` | | `Vaadin 24.0.0 - 24.9.17` | `Upgrade to 24.9.18` | | `Vaadin 24.10.0 - 24.10.3` | `Upgrade to 24.10.4` | | `Vaadin 25.0.0 - 25.0.11` | `Upgrade to 25.0.12` | | `Vaadin 25.1.0 - 25.1.4` | `Upgrade to 25.1.5 or newer` | Please note that Vaadin versions 10-13 and 15-22 are no longer supported and you should update either to the latest 23, 24, or 25 version. | Maven coordinates | Vulnerable version | Fixed version | |---|---|---| | `com.vaadin:flow-plugin-base` | `23.0.0 - 23.6.10` | `≥ 23.6.11` | | `com.vaadin:flow-plugin-base` | `24.0.0 - 24.9.17` | `≥ 24.9.18` | | `com.vaadin:flow-plugin-base` | `24.0.0 - 24.10.3` | `≥ 24.10.4` | | `com.vaadin:flow-plugin-base` | `25.0.0 - 25.0.11` | `≥ 25.0.12` | | `com.vaadin:flow-plugin-base` | `25.1.0 - 25.1.4` | `≥ 25.1.5` | | `com.vaadin:flow-maven-plugin` | `23.0.0 - 23.6.10` | `≥ 23.6.11` | | `com.vaadin:flow-maven-plugin` | `24.0.0 - 24.9.17` | `≥ 24.9.18` | | `com.vaadin:flow-maven-plugin` | `24.0.0 - 24.10.3` | `≥ 24.10.4` | | `com.vaadin:flow-maven-plugin` | `25.0.0 - 25.0.11` | `≥ 25.0.12` | | `com.vaadin:flow-maven-plugin` | `25.1.0 - 25.1.4` | `≥ 25.1.5` | | `com.vaadin:flow-gradle-plugin` | `24.0.0 - 24.9.17` | `≥ 24.9.18` | | `com.vaadin:flow-gradle-plugin` | `24.0.0 - 24.10.3` | `≥ 24.10.4` | | `com.vaadin:flow-gradle-plugin` | `25.0.0 - 25.0.11` | `≥ 25.0.12` | | `com.vaadin:flow-gradle-plugin` | `25.1.0 - 25.1.4` | `≥ 25.1.5` |
