CVE-2026-124694: Progress Kendo UI for jQuery PropertyGrid XSS in bound values

CVE-2026-124694 · Severity: high · CVSS 7.1 · Published 2026-11-11

Kendo UI for jQuery is a component library that developers use to build interactive web applications. The PropertyGrid component fails to properly encode user-supplied data when displaying bound property values and descriptions, allowing an attacker to inject malicious JavaScript. When a user views a PropertyGrid containing this malicious data, the JavaScript executes in their browser context, potentially exposing sensitive information or allowing unauthorized modifications to visible data.

Technical details

The vulnerability is a cross-site scripting (XSS) flaw in the PropertyGrid component where bound property values and the items[].description field are not HTML-encoded in default configuration. An attacker who can control these values (through data binding or API input) can inject JavaScript that executes when the grid is rendered. No user interaction beyond viewing the grid is required; exploitation depends on the ability to influence the bound data.
