AI-Discovered PHP Flaw Shuts Global Sites
On October 21-22, 2026, a critical PHP vulnerability—found using AI—forced government and corporate websites worldwide offline, including in Europe and the US, as operators rushed to patch it. The flaw, undetected for over a decade, allows server intrusion without login; US authorities advised offline transition if immediate updates weren't possible, and Korea's KISA recommended security updates. Korean media emphasize that while AI uncovered the issue, hackers could similarly exploit AI for large-scale attacks, raising widespread concern.
