# Kendo UI for jQuery: Chart tooltip lets injected markup run JavaScript

Link for people: https://infrastack.ai/live/CVE-2026-124697 (this .md is for agents)

Kendo UI for jQuery's Chart shared tooltip renders bound category and series-name values as raw HTML instead of text. An attacker who can influence those values can make script run in a user's browser when the shared tooltip is displayed.

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

## How to check

- Look for the `kendo.all.min.js` or `@progress/kendo-ui` package version in your project's `package.json` and lockfile
- Check whether any Chart uses a shared tooltip with data that users or external sources can influence
- Versions up to `2026.3.1015` are reported as the latest vulnerable line; `2016.2.607` or earlier may be affected but are unverified

## Fix

- Kendo UI for jQuery: move to `2026.4.1111`

## Timeline

- 2026-11-12T17:39:37+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-124697

## From the sources

In Progress Kendo UI for jQuery, Chart shared-tooltip rendering treats bound category and series-name values as raw HTML. An attacker who can influence values consumed by an affected Chart can inject markup that executes as JavaScript when a user displays the shared tooltip. Successful exploitation may compromise the confidentiality and integrity of data available in the user's browser context. Version 2016.2.607 or earlier may be affected, but earlier releases have not been verified. The latest vulnerable version is 2026.3.1015; the issue is fixed in version 2026.4.1111.
