Demonstrates how the float and clear CSS rules can be used to position page breaks in an editable document. This is the same technique that is used by Tiptap's PageKit extension.

Two important takeaways from CVE-2025-55182
We now have a public POC for CVE-2025-55182, the React Server vulnerability that allows remote code execution on affected servers. The details of how the exploit works are fascinating, and they highlight a couple of important but obscure facts about JavaScript itself that all JS developers should be aware of so that we hopefully don't make the same mistakes in our own code.
It's important to be aware that this type of vulnerability can also affect client-side code (XSS) in addition to server-side code (RCE).
Just a reminder for anyone using Slate:
