Description
In Progress® Kendo® UI for jQuery versions prior to 2026.4.1111, kendo.init() compiles data-* attribute values with new Function when an invalid JSON object is supplied. An attacker with low privileges who can control these attribute values can inject JavaScript that executes during declarative widget initialization when a user loads or interacts with an affected page. Successful exploitation can compromise the confidentiality and integrity of data accessible in the user's browser context. The issue was reported in version 2022.3.1109; the first affected release has not been established.
