In Vaadin Framework 7 and 8, the Action class is a general-purpose class that may be used by multiple components. The fixed versions sanitize captions by default and provide an API to explicitly enable HTML content mode for backwards compatibility.

In Vaadin 23 and newer, the Action class is only used by the Spreadsheet component. The fixed versions sanitize HTML using Jsoup with a relaxed safelist.

Vaadin 14 is not affected as Spreadsheet component was not supported.

Users of affected versions should apply the following mitigation or upgrade. Releases that have fixed this issue include:

Product version
Vaadin 7.0.0 - 7.7.49
Vaadin 8.0.0 - 8.29.1
Vaadin 23.1.0 - 23.6.5
Vaadin 24.0.0 - 24.8.13
