Summary
The default configuration of the TreeGrid component uses Object::toString as a key in client-side and server communication in Vaadin, potentially disclosing values that should not be available on the client side. Affected versions include Vaadin 14.8.5-14.8.9, 22.0.6-22.0.14, 23.0.0.beta2-23.0.8, and 23.1.0.alpha1-23.1.0.alpha4.
Risk Assessment
An attacker may gain access to sensitive data that should not be visible in the user's browser, potentially breaching information confidentiality. The risk affects Vaadin applications using the TreeGrid component in its default configuration.
Recommendation
Upgrade Vaadin to a version containing the fix or change the TreeGrid component configuration so it does not use Object::toString as a key. Verify that no sensitive data is sent to the client.
