AI models uncover critical PHP vulnerabilities, prompting global web security scramble

AI models, including OpenAI's GPT-5.6 Sol and Google's Gemini 4 Argon (via Wiz.io), have identified critical vulnerabilities in PHP, a foundational programming language underpinning a significant portion of the internet. This discovery has triggered a global cybersecurity emergency, with governments and web administrators rushing to patch systems and, in some cases, taking websites offline. The vulnerabilities, collectively dubbed "PHP2Shell" by Wiz.io, are considered highly impactful due to PHP's widespread use. OpenAI and Wiz.io, both first-party sources, confirmed the AI-driven discovery and its severity, leading to coordinated warnings from entities like the US government and the NSA. The identified flaws allow for remote code execution (RCE), posing a severe risk to data and system integrity. While the immediate focus is on patching, the incident highlights the dual potential of advanced AI in both discovering and potentially exploiting such weaknesses.
