CVE-2026-106138 — Cross-Site Scripting via Chart Tooltip in KendoReact

Description (CNA)

In Progress® KendoReact (@progress/kendo-react-charts) starting with version 1.1.0 and prior to 16.2.0, the default Chart tooltip renders the formatted point value as raw HTML without encoding, in both the single-point and the shared tooltip. An attacker with low privileges who can influence a string value bound to the chart can supply HTML containing event handlers that execute JavaScript in a user's browser when the user hovers over the affected data point. Successful exploitation can compromise the confidentiality and integrity of data accessible to the affected application.
