# Kendo UI for jQuery: chart tooltip runs injected HTML and script

Link for people: https://infrastack.ai/live/CVE-2026-124698 (this .md is for agents)

The Kendo UI for jQuery Chart default tooltip renders point values as raw HTML, so a string value can carry markup that runs as JavaScript when a user hovers over the point. An attacker who controls the point values can read or change data in the victim's browser session.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Kendo UI for jQuery version in `package.json` or the bundled `kendo.all.min.js` header.
- Look for Chart widgets that bind user-influenced strings as point values with the default tooltip.

## Fix

- Kendo UI for jQuery: move to `2026.4.1111` or later.

## Timeline
