# Mendix Studio Pro: web pages can trigger actions on local MCP server

Link for people: https://infrastack.ai/live/CVE-2026-112137 (this .md is for agents)

The MCP Server in Mendix Studio Pro does not validate Content-Type and Origin headers on incoming HTTP requests. A malicious web page can make a developer's browser send unauthorized requests to that local server and trigger unintended actions.

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

## Affected

- vendor:Mendix Studio Pro affected range not listed fixed no fixed version listed

## How to check

- Check the installed Mendix Studio Pro version. Versions from `11.15.0` up to `11.16.0` (exclusive) and from `11.12.6` up to `11.12.7` (exclusive) are affected.
- Check whether the MCP Server is running locally while you browse the web.

## Fix
