We're aware of recently announced PHP vulnerabilities. We have mitigations in place, and have patched our managed services, including Web Hosting and Managed Hosting for WordPress.
If you manage your own server or VPS, you'll need to apply the PHP update yourself.
This incident affects: Web Hosting (Web Hosting, Web Hosting Plus), Advanced Hosting (Virtual Private Server (VPS)), and Managed WordPress Hosting (Managed WooCommerce Stores, UI).
