Summary

Mendix Studio Pro 11 and 11.12 have a flaw in their MCP Server, which does not properly check the Content-Type and Origin headers on incoming requests. A remote attacker can exploit this without logging in by tricking a user into visiting a malicious web page, which can then make the local MCP Server carry out unintended actions.

Read the original description

A vulnerability has been identified in Mendix Studio Pro 11 (All versions >= V11.15.0 < V11.16.0), Mendix Studio Pro 11.12 (All versions >= V11.12.6 < V11.12.7). The affected products MCP Server does not properly validate Content-Type and Origin headers on incoming HTTP requests, leaving it vulnerable to Cross-Site Request Forgery (CSRF). This could allow a malicious web page to trick a user's browser into sending unauthorized requests and executing unintended actions on the local MCP Server.

Check your systems with an agent

Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.

Check whether my systems are affected by CVE-2026-112137 (A vulnerability has been identified in Mendix Studio Pro 11 (All versions >= V11.15.0 < V11.16.0), Mendix Studio Pro 11.12 (All versions…), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

What cve.now has for CVE-2026-112137 (entry last updated 2026-11-10):
Affected:
- Siemens Mendix Studio Pro 11: from V11.15.0, fixed in V11.16.0
- Siemens Mendix Studio Pro 11.12: from V11.12.6, fixed in V11.12.7
Fixed versions: V11.16.0, V11.12.7.
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
CISA KEV: CVE-2026-112137 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-112137 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:
- https://cert-portal.siemens.com/productcert/html/ssa-710379.html
Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.

Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.
