# Kendo UI for jQuery Gantt: task titles run as HTML in editor

Link for people: https://infrastack.ai/live/CVE-2026-124691 (this .md is for agents)

The Parent dropdown in the Gantt task editor renders task titles as raw HTML instead of text. An attacker who can set a task title can make script run in the browser of a user who opens the task editor, exposing data in that 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 your package manifest or lockfile, for example `npm ls @progress/kendo-ui` or `npm ls @progress/kendo-ui-for-jquery`.
- Confirm whether the app uses the Gantt widget with the task editor's Parent dropdown.

## Fix

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

## Timeline

- 2026-11-12T17:39:37+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-124691

## From the sources

In Progress Kendo UI for jQuery Gantt, the task editor's Parent dropdown renders task titles as HTML. An attacker who can influence a task title shown in the dropdown can cause attacker-controlled markup to execute as JavaScript when a user opens or interacts with the task editor. Successful exploitation may compromise the confidentiality and integrity of data available in the user's browser context. The first affected version is 2020.3.915; the latest vulnerable version is 2026.3.1015. The issue is fixed in version 2026.4.1111.
