Severe security flaws in the PHP programming language have prompted European public authorities and organizations to take websites offline as emergency patches are deployed.

Cybersecurity authorities and developers have warned of severe security vulnerabilities in PHP, the widely used programming language behind millions of websites and content management systems. The security flaws have prompted public institutions, including German state ministries, municipal governments, and university hospitals, to temporarily take their websites offline to mitigate potential risks.

Proactive website shutdowns and defensive measures have also been reported across Europe, including in France, the Netherlands, and Denmark. IT security firms and emergency response teams warned that the vulnerabilities could allow remote exploitation if unpatched. Software maintainers announced emergency fixes for the affected systems as administrators worked to secure digital infrastructure worldwide.
