Summary
In the Vaadin Upload component, when the start listener is used to validate metadata about an incoming upload, it is possible to bypass the upload validation. Affected versions include Vaadin 7.0.0-7.7.47, 8.0.0-8.28.1, 14.0.0-14.13.0, 23.0.0-23.6.1, and 24.0.0-24.7.6.
Risk Assessment
An attacker can upload files that should be rejected by validation, potentially introducing malicious content into the application. The risk affects Vaadin applications using the Upload component with validation in the start listener.
Recommendation
Upgrade Vaadin to version 7.7.48, 8.28.2, 14.13.1, 23.6.2, or 24.7.7 (or newer). Users of unsupported versions 10-13 and 15-22 should move to the latest 14, 23, or 24 version.
Other vulnerabilities in Vaadin
See all- CVE-2026-91860Medium
A prototype pollution vulnerability exists in the deep merge helpers of Vaadin Charts and Vaadin Component Base. Merging an object the application does not control into a chart configuration or into a component's i18n property writes onto Object.prototype, making the injected properties visible to every object in the running application.
- CVE-2025-15022Medium
Action captions in Vaadin accept HTML by default but were not sanitized, potentially allowing Cross-site Scripting (XSS) if caption content is derived from user input. In Vaadin Framework 7 and 8, the Action class is general-purpose, while in Vaadin 23 and newer it is only used by the Spreadsheet component. Fixed versions sanitize captions by default and provide an API to explicitly enable HTML content mode.
- CVE-2023-25500Low
In Vaadin, in many versions, a vulnerability allows information disclosure of class and method names in RPC responses by sending modified requests.
- CVE-2023-25499Medium
In Vaadin, adding non-visible components to the UI on the server side causes their content to be sent to the browser, potentially leading to information disclosure. Affected versions include 10.0.0-10.0.22, 11.0.0-14.10.0, 15.0.0-22.0.28, 23.0.0-23.3.12, 24.0.0-24.0.5, and 24.1.0.alpha1-24.1.0.beta1.
- CVE-2022-29567Medium
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.
