AI Found Bugs Hidden in 70% of the Internet Since 2004

Two critical vulnerabilities in PHP — which powers roughly 70% of known websites — were found by AI tools and disclosed this week after sitting undetected in the code since 2004. Government sites in France, the Netherlands, Belgium, and Australia went offline as a precaution after details leaked early, and 1.5 million hosts remained unpatched when fixes shipped. The same AI systems that found the bugs also accelerate writing exploits — compressing the window between disclosure and attack.
