CVE-2026-48192 Siemens CVE debrief

Who should care

Organizations using Mendix Studio Pro, especially those in industrial control systems and critical infrastructure sectors, should be aware of this vulnerability and take necessary actions to mitigate potential attacks. They should prioritize updating to patched versions, validating project files, and implementing compensating controls to mitigate potential attacks. Security teams should review their deployments and ensure they are running patched versions.

Technical summary

Affected versions of Mendix Studio Pro do not properly validate or sanitize project files processed during the build pipeline, allowing an attacker to execute arbitrary code in the context of the user. This vulnerability can be exploited if an attacker tricks a user into opening and running a specially crafted malicious project locally on their system. Organizations using Mendix Studio Pro should prioritize updating to patched versions and validating project files.

Defensive priority

Organizations using Mendix Studio Pro should prioritize updating to patched versions, validating project files, and implementing compensating controls to mitigate potential attacks.

Recommended defensive actions

• Update to V10.24.21 or later version for Mendix Studio Pro 10.24
• Update to V11.6.7 or later version for Mendix Studio Pro 11.6
• Validate and sanitize project files processed during the build pipeline
• Implement compensating controls to mitigate potential attacks
• Monitor for suspicious project file activity
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Track exceptions, retest remediated assets, and close the item only after evidence is documented

Evidence notes

The CVE record and CISA CSAF advisory provide details on the vulnerability in Mendix Studio Pro. Evidence is based on official records from CISA and Siemens. The vulnerability affects Mendix Studio Pro versions that do not properly validate or sanitize project files processed during the build pipeline. This could allow an attacker who tricks a user into opening and running a specially crafted malicious project locally on their system to execute arbitrary code in the context of that user. Organizations should verify their deployments and ensure they are running patched versions.
