Description

In Progress® Kendo® UI for jQuery releases starting with R1 2020 and prior to 2026.3.1015, the ListBox default item template renders the bound dataTextField value as raw HTML without encoding. An attacker who can modify the bound data can supply HTML containing event handlers that execute JavaScript in a user's browser when the affected list item is rendered. Successful exploitation can compromise the confidentiality and integrity of data accessible to the affected application. This issue is fixed in version 2026.3.1015.
