Kudos to our CDN & Security teams working day & night to protect the internet from React2Shell attacks.
Our WAF continues to get stronger, in collaboration with security researchers worldwide. It protects against non-trivial bypasses, making it a remarkably capable first line of defense (and not just for these vulns, but existing & future rules.)
That said: please patch your applications!
