Mendix Cloud Platform Maintenance - Wave 5

Completed - The scheduled maintenance has been completed.
Nov 13, 16:00 UTC

In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Nov 13, 08:00 UTC

Scheduled - Maintenance is scheduled for the application infrastructure of Mendix Cloud. The maintenance will improve the security and stability of the Mendix Cloud platform.

We normally announce maintenance two weeks in advance. This time, we are making an exception and giving shorter notice. The patches in this maintenance contain critical security fixes for recently published vulnerabilities (CVEs), and we want to apply them as soon as possible, and before the holiday season begins, to keep your applications and data protected. We apologize for any inconvenience and appreciate your understanding.

This upgrade is executed on a platform level, which means there is no flexibility in the time period, but you can move your app early yourself (see below). An 8-hour maintenance window is planned.

Start: Friday, Nov 13th, 2026, 08:00 UTC
End: Friday, Nov 13th, 2026, 16:00 UTC

Impact on Mendix apps

During the maintenance, the Runtime Engines (application instances) of your Mendix applications will be restarted on the updated application infrastructure. This is executed automatically in no specific order. To ensure continuous availability for all customer applications, the underlying infrastructure upgrades will be performed in a rolling fashion. This means the rolling upgrade process ensures no downtime for both multi-instance applications (by restarting only one Runtime Engine at a time) and single-instance applications.

While the rolling nature of these upgrades is designed to minimize impact, a small number of users might experience brief, intermittent networking disruptions or 502 errors as underlying services are rotated. These are typically temporary and self-correcting.

Moving early

If the scheduled maintenance window is inconvenient for your application, you may opt to move to the updated infrastructure ahead of time. The updated application infrastructure will be available starting Thursday, November 5th, 2026, 12:00 UTC.

Any application that is (re)deployed or restarted after this time will be scheduled on the updated infrastructure and will not be restarted again during the maintenance window. This allows you to control the timing of the restart and avoid impact during business-critical hours.

Please note that, even when moving early, a small number of users may still experience brief, intermittent 502 errors during the scheduled maintenance window due to the rotation of underlying platform services. These events are expected to be temporary and self-correcting.

Security update: Critical Java patch update

Resolved - This incident has been resolved.
Nov 10, 09:59 UTC

Monitoring - The fix for Java 11 has been released and rolled out across Mendix Cloud. Java 11 now includes the October 2026 Critical Patch Update, like Java 25, 21 and 17.

What you need to do
If your app is running on Java 11, you should redeploy your app. You can find the Java version used for your environment on the Environment Details page (https://docs.mendix.com/developerportal/deploy/environments-details/#application-status). You can redeploy the same package that is already running on your environment, or build and deploy a new package. A restart is not enough!

We recommend doing this in your usual order, so you can check that your applications still work before updating production:
1. Test environment
2. Acceptance environment
3. Production environment

Deployment requirements
To apply these security fixes, you must perform a regular deployment (non-Zero Downtime Deployment). Zero Downtime Deployment (ZDT) will not apply these security fixes, even when redeploying an existing deployment package. If you have already performed a Zero Downtime Deployment to apply these fixes, please redeploy using the regular deployment process. A regular deployment causes a short period of downtime while the application restarts, so please plan accordingly.

If you have any questions, feel free to contact support.
Nov 9, 18:31 UTC

Update - The fix for Java 17 has been released and rolled out across Mendix Cloud. If your app is running on Java 17, please follow the redeploy instructions as listed in the original statuspage message. For Java 11, we're waiting for an update from our vendors. Once these updates are available, we will update the Java versions used on Mendix Cloud.
Oct 28, 09:31 UTC

Identified - What happened
On 20 October 2026, Oracle has released an October 2026 Critical Patch Update (https://blogs.oracle.com/security/october-2026-critical-patch-update-released) that includes multiple fixes for Java versions that are in use by Mendix apps.

Who is affected
All customers with applications running on Mendix Cloud.

What we did
We have updated the Java version for Java 25, Java 21 and Java 17. These new versions include the critical patch updates.
For Java 11, we're waiting for an update from our vendors. Once these updates are available, we will update the Java versions used on Mendix Cloud.

What you need to do
If your app is running on Java 17, 21 or Java 25, you should redeploy your app. You can find the Java version used for your environment on the Environment Details page (https://docs.mendix.com/developerportal/deploy/environments-details/#application-status). You can redeploy the same package that is already running on your environment, or build and deploy a new package. A restart is not enough!

We recommend doing this in your usual order, so you can check that your applications still work before updating production:
1. Test environment
2. Acceptance environment
3. Production environment

If your app is running on Java 11, you should keep an eye on this Statuspage incident. We will update this when we release new Java versions on Mendix Cloud. These updates will include instructions for the specific Java versions.

Deployment requirements
To apply these security fixes, you must perform a regular deployment (non-Zero Downtime Deployment). Zero Downtime Deployment (ZDT) will not apply these security fixes, even when redeploying an existing deployment package. You do not need to create a new deployment package. You can redeploy your existing package using the regular deployment process. If you have already performed a Zero Downtime Deployment to apply these fixes, please redeploy using the regular deployment process. A regular deployment causes a short period of downtime while the application restarts, so please plan accordingly.

If you have any questions, feel free to contact support.

Mendix on Kubernetes and Mendix on Azure building issue

Resolved - A fix has been released. Newly built apps on Mendix on Kubernetes and Mendix on Azure start normally again.
If an environment failed to start, deploy the app to that environment again. This builds a new image that contains the fix. Restarting the environment is not enough, because a restart reuses the faulty image.
Environments that kept running are not affected and do not need any action. You can deploy as usual again.
If you pull the Mendix runtime base images through your own registry mirror, sync them again before you redeploy.
Nov 5, 09:54 UTC

Monitoring - A fix has been implemented and we are monitoring the results.
Nov 5, 09:45 UTC

Identified - We identified the root cause and prepared a fix. It is currently propagating through our release pipeline.
Nov 5, 08:10 UTC

Investigating - We are curently investigating the issue.

Do not deploy or redeploy running environments until further notice. Restarting environments is safe. Do not downgrade the Operator, downgrading the Operator is unsupported an will not resolve the issue.

Security update: compromised eMudhra certificates blocked for Mendix Cloud apps

Resolved - This incident has been resolved.
Nov 4, 09:24 UTC

Monitoring - What happened

A certificate authority called eMudhra generated the cryptographic keys for eight of its intermediate certificates incorrectly, that caused the certificates to become compromised. Java, which Mendix apps run on, trusted these certificates by default. Someone able to intercept an app's outgoing connection could pose as the server it was calling.

Who is affected

Only the outgoing connections your app makes over HTTPS, for example REST or web service calls, or other integrations with external systems. Traffic coming in to your app, such as users opening it in a browser, is not affected.

What we did

We have updated the Mendix Cloud build process so that apps built from now on no longer trust the compromised certificates. We have also updated the underlying OS base image. This was released on 22 Oct at 17:30 UTC.

What you need to do

The fix is added when your app is deployed, so apps that are already running only get it when you redeploy. You can redeploy the same package that is already running on your environment, or build and deploy a new package. A restart is not enough!

If your app makes outgoing calls to other systems, please redeploy it. We recommend doing this in your usual order, so you can check that your integrations still work before production:

1. Test environment
2. Acceptance environment
3. Production environment

If your app does not make outgoing calls, no action is needed. It will receive the update at its next regular deployment.

Deployment requirements

To apply these security fixes, you must perform a regular deployment (non-Zero Downtime Deployment). Zero Downtime Deployment (ZDT) will not apply these security fixes, even when redeploying an existing deployment package. You do not need to create a new deployment package. You can redeploy your existing package using the regular deployment process. If you have already performed a Zero Downtime Deployment to apply these fixes, please redeploy using the regular deployment process. A regular deployment causes a short period of downtime while the application restarts, so please plan accordingly.

What to expect after redeploying

If one of the systems your app calls uses a certificate issued by one of the affected eMudhra authorities, the connection will now fail. In that case, ask the owner of that system to replace its certificate.

If you have any questions, feel free to contact support.
