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. Users of affected versions should apply the following mitigation or upgrade. Releases that have fixed this issue include: Product version Vaadin 23.0.0 - 23.6.13 Vaadin 24.0.0 - 24.9.20 Vaadin 24.10.0 - 24.10.9 Vaadin 25.0.0 - 25.1.11 Vaadin 25.2.0 - 25.2.6 Mitigation Upgrade to 23.6.14 Upgrade to 24.9.21 Upgrade to 24.10.10 Upgrade to 25.1.12 Upgrade to 25.2.7 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, 25 version.
