Due to a critical security vulnerability in the widely used PHP programming language, multiple government websites across Europe and other regions were forced to go offline on Wednesday, with site operators taking urgent measures to secure their systems. The PHP development team announced on local time Tuesday that two critical security flaws had been discovered, urging users to update immediately once patches were released. On Wednesday, the team confirmed that the new PHP version fixing the vulnerabilities was officially launched. However, amid reports that hackers were exploiting the flaws to breach websites, government agencies in the Netherlands, Finland and other countries had preemptively shut down some sites before the patch’s release.

Around 43% of global websites are powered by WordPress, covering blogs, small business sites, government portals, e-commerce platforms and news sites.
