A critical vulnerability in PHP, affecting up to 70% of the world's websites, has led to millions of attempted exploits since its disclosure on October 19, 2026. The UK government reported that over 30 services were taken offline as a precaution while patches were applied. Telecommunications operator Orange and various organizations in multiple countries, including Japan and several EU nations, also suspended services to mitigate risks. Researchers indicated that hackers had attempted to exploit the vulnerabilities even before they were publicly disclosed. The US National Security Agency warned that the flaws could allow attackers to seize control of web servers and steal sensitive data. Although no successful hacks have been confirmed, the scale of the vulnerability is unprecedented, prompting widespread government and corporate action to secure systems. The PHP development team released patches on October 19, urging immediate adoption. Matthew Prince from Cloudflare noted thousands of exploit attempts were detected shortly after the flaws were made public.
