Cross-Site Scripting in Kendo UI for jQuery PropertyGrid Values and Descriptions

In Progress Kendo UI for jQuery versions 2026.3.1015 up to, but not including, 2026.4.1110, PropertyGrid does not encode bound property values and items[].description in its default configuration. An attacker who can influence either value can cause JavaScript to execute when a user views the grid. Successful exploitation may compromise the confidentiality and integrity of data available in the user's browser context. The first affected release has not been established.
