Symbolic imageMillions of exploit attempts follow AI-found PHP flaws as sites return online
Two critical PHP flaws found with AI tools forced agencies and firms to pull websites offline on Wednesday. Cloudflare reports millions of exploit attempts, while many sites are back.
The flaws, tracked as CVE-2026-109618 and CVE-2026-109619 and dubbed "PHP2Shell", let attackers run code on a server without logging in; the PHP security team rates both 9.2 out of 10. PHP's developers released a fix on Wednesday, 21 October, after Germany's BSI and the US NSA urged operators to patch or go offline. Cloudflare chief Matthew Prince told Sky News of a few thousand attempts in the ten hours before the announcement, hundreds of thousands two hours after it, and millions since. Many sites are back online after patching.

Handelsblatt reports the flaws were long known but rated non-critical, and AI let researchers chain them into an attack path. Citing the Wall Street Journal, FAZ says a researcher found them with an OpenAI model.
German fallout
