Siemens Mendix Studio Pro Build Pipeline Code Injection Vulnerability

Technical Analysis

CVE-2026-48192 (CVSS 3.1: 5.4, AV:N/AC:H/PR:H/UI:R/S:C/C:N/I:H/A:N) stems from improper validation and sanitization of project files during the Mendix Studio Pro build pipeline, classified as CWE-94 Improper Control of Generation of Code. An attacker who convinces a victim to open and build a malicious project locally can achieve arbitrary code execution in the context of the logged-in user, potentially compromising the developer workstation. Multiple version branches (10.11–11.11) are affected, with fixes available only for the 10.24 and 11.6 branches; other affected versions currently have no fix planned. Because Mendix is a low-code platform frequently used to build enterprise applications—including those that integrate AI/LLM components, RAG pipelines, or agent-driven automation workflows—compromise of a developer's build environment could lead to injection of malicious logic into downstream applications or theft of API keys and credentials used by connected AI agents, making this agent-relevant for organizations embedding Mendix-built apps into AI-driven workflows.

Affected Systems

Siemens Mendix Studio Pro versions 10.11 through 10.23 (all), 10.24 prior to V10.24.21, 11.0 through 11.5, 11.6 prior to V11.6.7, and 11.7 through 11.11

Indicators of Compromise

• No specific file hashes, IPs, or domains provided; indicator is a maliciously crafted Mendix project file used during the build pipeline process.

Remediation Steps

1. 1

   Update Mendix Studio Pro 10.24 branch

   Update to version 10.24.21 or later as provided by Siemens.

2. 2

   Update Mendix Studio Pro 11.6 branch

   Update to version 11.6.7 or later as provided by Siemens.

3. 3

   Apply vendor guidance for unpatched branches

   For versions where no fix is currently planned, avoid opening or building untrusted or unverified Mendix project files.

4. 4

   Restrict project file sources

   Only open and build Mendix projects from trusted, verified sources to prevent social engineering-based exploitation.

5. 5

   Follow Siemens operational guidelines

   Implement Siemens' Industrial Security operational guidelines and isolate development environments from untrusted networks.

6. 6

   Network segmentation

   Minimize network exposure for control system and development environments, ensuring they are not directly accessible from the internet.
