In Progress® Kendo® UI for jQuery releases starting with v2020.1.114 and prior to 2026.3.1015, the Badge text method renders string values as raw HTML without encoding, including values supplied through text binding. An attacker who can modify data bound to a Badge can supply HTML containing event handlers that execute JavaScript in a user's browser when the Badge renders the value. Successful exploitation can compromise the confidentiality and integrity of data accessible to the affected application. This issue is fixed in version 2026.3.1015.
