How to Fix GHSA-crh4-294p-vcfq

To remediate this vulnerability, upgrade all affected Vaadin text field 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.

com.vaadin:vaadin-text-field-flow fixed: 2.3.3 
<dependency>
    <groupId>com.vaadin</groupId>
    <artifactId>vaadin-text-field-flow</artifactId>
    <version>2.3.3</version>
</dependency>
com.vaadin:vaadin-text-field-flow fixed: 4.0.3 
<dependency>
    <groupId>com.vaadin</groupId>
    <artifactId>vaadin-text-field-flow</artifactId>
    <version>4.0.3</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-crh4-294p-vcfq, 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 text field flow in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.3.3), 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Vaadin text field flow, 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

Unsafe validation RegEx in `EmailField` component in `com.vaadin:vaadin-text-field-flow` versions 2.0.4 through 2.3.2 (Vaadin 14.0.6 through 14.4.3), and 3.0.0 through 4.0.2 (Vaadin 15.0.0 through 17.0.10) allows attackers to cause uncontrolled resource consumption by submitting malicious email addresses. - https://vaadin.com/security/cve-2021-31405
