Security update

Hosting Partner Update Status.

On October 21, 2026, PHP released fixes for two critical security issues (CVE-2026-109618 and CVE-2026-109619). PHP is the language behind Craft CMS and WordPress, so most websites need this update. Each hosting platform has to make the fix available or apply it. This page shows where each of our hosting partners stands. It checks their public status updates automatically.

Railway

Delayed by provider

Mostly Serious applies the fix

Where things stand: The updated server images are now available, but Railway has paused builds and deployments on its platform during an outage, so the update can't be deployed until Railway resolves it.

Next step: Once the updated images are published and Railway builds are running, we redeploy each site on Railway and confirm it's running the fixed version.
