Two critical security flaws in PHP forced several European government websites to go offline on Wednesday. The vulnerabilities are identified as CVE-2026-109618 and CVE-2026-109619. Each bug received a severity rating of 9.2 out of 10.
PHP is the core programming language behind most websites. The language powers major content management platforms like WordPress, Drupal, Joomla, and Magento. Because of its widespread use, these vulnerabilities put many global websites at immediate risk.
The security flaws allow malicious actors to execute arbitrary code on vulnerable servers without authentication credentials. Cyber emergency teams at CERT-EU confirmed that every PHP version starting from PHP 5 onward remains vulnerable. Furthermore, web hosting firm GoDaddy warned that attackers could steal sensitive data, deface online portals, or gain full control over affected servers.

Government Agencies Respond to Critical Vulnerabilities
Government agencies in the Netherlands and Finland took down public websites as a precaution. These temporary shutdowns did not indicate active security breaches. Instead, officials took systems offline to prevent damage while waiting for security patches.
Leading European cybersecurity bodies released a joint statement regarding the situation. ENISA, CERT-EU, the European Commission, and Europol EC3 urged organizations to install PHP updates immediately. Officials advised isolating internet-facing applications from public networks if patching experienced delays. The advisory warned that many software tools integrate PHP in the background, making detection difficult.

Federal and Global Authorities Issue Urgent Advisories
The FBI’s Cyber Division released its own security advisory. The agency instructed administrators to remove unpatched systems from public networks until applying fixes. Federal agents urged IT teams to monitor server activity for unauthorized command shells launched by PHP processes.
Australia’s national cybersecurity agency published matching guidance for local systems. Australian authorities confirmed that no active exploitation had been observed within their jurisdiction.
Websites in Pakistan also face significant exposure to these vulnerabilities. Numerous government portals, financial institutions, and e-commerce platforms rely on PHP or WordPress frameworks. Security experts advise Pakistani organizations to audit their PHP installations and apply updates immediately.
PHP maintainers released official software patches on October 21, 2026, at 13:40 UTC. Security researchers at watchTowr confirmed they successfully reproduced the exploits in test environments. No confirmed breaches have occurred yet, although preliminary reports of scanning attempts have surfaced online.
