Critical PHP Vulnerabilities Trigger Worldwide Rush to Update Systems

Critical flaws in PHP, a programming language used by 69% of websites, prompted urgent security warnings and temporary shutdowns as maintainers released patches. Some sites, including Pinboard and Wikipedia, went offline while preparing updates. Security firms reported active exploitation, though the U.S. Cybersecurity and Infrastructure Security Agency said it had not observed attacks at publication time. Organizations running PHP should apply official patches promptly, review vendor advisories and consider restricting internet exposure or isolating systems if they cannot update.
