# KendoReact Chat: unsafe URL in quick action runs JavaScript in app

Link for people: https://infrastack.ai/live/CVE-2026-106136 (this .md is for agents)

The Chat component of the KendoReact UI library (versions 0.6.0 through 16.1.0) does not sanitize a URL passed to an openUrl quick action. An attacker who can post Chat messages can make a user's click run arbitrary JavaScript in the application's origin.

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

## How to check

- Check whether `@progress/kendo-react-conversational-ui` is in `package.json` or the lockfile, and read its version.
- Look for uses of the Chat component that render quick actions with `openUrl` from user-supplied message content.

## From the sources

Cross-Site Scripting (XSS) in the Chat component (@progress/kendo-react-conversational-ui) in Progress Software KendoReact versions 0.6.0 through 16.1.0 allows a low-privileged attacker who can supply Chat messages to execute arbitrary JavaScript in the origin of the application via an unsafe URL in an openUrl quick action, which runs when a user clicks the action.
