Who is affected?
All WoodWing Cloud customers using Studio. This applies to Production and Non-Production Environments in all regions (EU, US and AUS).
When?
Studio environments will be taken offline on Wednesday 21 October 2026 at 10:51 CEST. We expect to restore service after the PHP release becomes available. We will update this article as soon as environments are back online.
What to expect
Studio will be unavailable during this period. Integrations that connect to Studio Server, including InDesign Server automation and Connect Apps, will not work until service is restored.[If applicable:] Assets environments are not affected and remain available.
Why is WoodWing doing this?
The PHP project has announced an upcoming security release addressing two critical vulnerabilities, both rated CVSS 9.2. Details of the vulnerabilities will only be published together with the fix. Because Studio Server runs on PHP, we have decided to take all Studio environments offline as a precaution until the fix is available and has been applied. We consider a short, planned interruption preferable to leaving environments exposed. PHP: News Archive - 2026
What is required?
No action is needed from you for your WoodWing Cloud environments. Please inform your users about the interruption.Customers running Studio Server on their own infrastructure are advised to follow the PHP security release and update PHP as soon as the fixed versions are published. We will publish updated installers and guidance separately.If you have any questions, please contact us via https://helpcenter.woodwing.com/hc/en-us/requests/new?ticket_form_id=12617

Update: Restoring Studio environments with IP-restricted access
While we wait for the PHP fix to be released, we are preparing to bring WoodWing Cloud Studio environments back online with access limited to approved IP addresses.
We will reach out to each customer shortly with instructions on what we need from you. Please keep an eye on your inbox.
Have a print deadline coming up? Contact support so we can give your environment priority.
Is there an email notification list we should be subscribed to to get early notification for events like this? I have a panicked newsroom with a surprise 503 error. Had I known about the upcoming downtime, I could've prepped them.
Hi Chris,

We would like to add that this PHP security issue is impacting Studio only. None of our other products are impacted.
