Summary

A missing authorization check in the Vaadin Spreadsheet component allows an authenticated user of an application that renders a spreadsheet to add or replace cell comments on a sheet that has protection enabled, including on cells that are locked. Writing a comment to a cell that does not exist yet also creates the row and the cell. Users of affected versions should apply the following mitigation or upgrade. Releases that have fixed this issue include: Product version Vaadin 23.1.0 - 23.6.13 Vaadin 24.0.0 - 24.9.21 Vaadin 24.10.0 - 24.10.9 Vaadin 25.0.0 - 25.1.11 Vaadin 25.2.0 - 25.2.6 Vaadin Framework 7 and 8 with the Spreadsheet add-on 2.0.0 - 3.1.0 Mitigation Upgrade to 23.6.14 Upgrade to 24.9.22 Upgrade to 24.10.10 Upgrade to 25.1.12 Upgrade to 25.2.7 or newer Upgrade the Spreadsheet add-on to 3.1.1 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.
