Global websites taken offline after critical PHP security flaws are discovered

International governments and agencies urged websites to address two critical vulnerabilities in the PHP programming language, which powers much of the internet. Due to the severity, bodies including the Finnish government, Edinburgh council, and the BBC have taken pages offline, while the Wikimedia Foundation temporarily shut down parts of Wikipedia. The flaws, which could provide a direct path to a server's file system or database, were discovered by AI tools through OpenAI's Patch the Planet program, involving researchers from Calif and Wiz, and had gone undetected for over a decade.
