Recent security research has brought attention to a previously unknown access-control weakness affecting certain Cloudflare-protected environments. The issue involves a specific request handling path that, under limited conditions, could allow traffic to reach backend hosts even when strict security rules are in place.

In some configurations, these requests were handled differently from standard web traffic, creating an unexpected route that bypassed normal filtering logic. Importantly, this issue does not indicate a failure of Cloudflare’s…
