Widespread PHP Flaw May Cause Many Site Outages Today
Matched: OpenAI
A critical pair of PHP vulnerabilities affecting roughly 70% of websites is being actively exploited, with working exploits already circulating. All PHP versions since 5.4 are affected, enabling remote code execution, denial-of-service, and data exposure. Fixes are available in PHP 8.5.12, 8.4.27, 8.3.36, and 8.2.35. Cloudflare implemented firewall protections early today, while government sites in Europe have already gone offline. Researchers compare the severity to the 2021 Log4Shell flaw.
