Description
In Progress® Kendo® UI for jQuery prior to 2026.3.1015, the TabStrip, Menu, and PanelBar components insert data source imageUrl values into single-quoted image src attributes without proper escaping. An attacker who can modify an image URL can inject additional HTML attributes, including event handlers, and execute JavaScript in a user's browser when the affected component renders the image. Successful exploitation can compromise the confidentiality and integrity of data accessible to the affected application. The earliest affected version has not been confirmed. This issue is fixed in version 2026.3.1015.
