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. This is tracked as CVE-2026-91403. 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. Tomorrow we will do another update to get the latest Java/JRE releases included.
What you need to do
The fix is added when your app is built, so apps that are already running only get it when you redeploy. 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.
A redeploy causes a short downtime while the app restarts, so you can plan it in a window that suits you.
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.

Scheduled Maintenance
Scheduled Platform Maintenance Oct 25, 2026 09:00-13:00 UTC
We will perform updates on our platform applications. During the maintenance window, you may not be able to sign in to Mendix Portal or Studio Pro. Parts of the Mendix Portal may not be available. Public APIs, administration of API credentials and security settings may also be temporarily unavailable.
It may also not be possible to deploy apps or administer your environments during this time.
In case you are affected, please retry your actions once the scheduled maintenance has been completed.

Mendix Cloud Platform Maintenance - Wave 5 Oct 26, 2026 08:00-16:00 UTC
Maintenance is scheduled for the application infrastructure of Mendix Cloud. The maintenance will improve the security and stability of the Mendix Cloud platform. 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: Monday, Oct 26th, 2026, 08:00 UTC
End: Monday, Oct 26th, 2026, 16:00 UTC
Impact on Mendix apps
During the maintenance, the Runtime Engines (application instances) of your Mendix applications will be restarted and redeployed to 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, Oct 22nd, 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.
