CVE-2026-106148 · Severity: medium · CVSS 5.4 · Published 2026-10-15

Progress Kendo UI for jQuery is a JavaScript library for building interactive web components. The TabStrip, Menu, and PanelBar components fail to properly escape image URL values, allowing an attacker who can control these URLs to inject malicious JavaScript code. When a user's browser renders the affected components, the injected code executes with the user's privileges, potentially stealing sensitive data or performing unauthorized actions.

## Technical details

The TabStrip, Menu, and PanelBar components in Kendo UI for jQuery insert unsanitized imageUrl data source values into single-quoted HTML image src attributes, enabling attribute injection attacks (CWE-80). An attacker with the ability to modify image URLs can inject event handlers (e.g., onerror) that execute arbitrary JavaScript when the component renders. This requires either authentication or a mechanism to control the data source, and user interaction to trigger the affected component's rendering.
