In Progress® Kendo® UI for jQuery prior to 2026.3.1015, Model.accept passes server-response keys to kendo.setter without guarding against unsafe object paths containing __proto__, constructor, or prototype. An attacker who can supply data accepted by an affected model can modify object prototype attributes and influence application behavior, potentially compromising the confidentiality and integrity of application data. The impact depends on how the application uses the modified objects, including in server-side JavaScript scenarios. The earliest affected version has not been confirmed. This issue is fixed in version 2026.3.1015.
