What Happened

On October 21, 2026, the PHP project disclosed two critical security vulnerabilities (together known as PHP2Shell, CVE-2026-109618 and CVE-2026-109619) with a CVSS v4 score of 9.2 out of 10. An unauthenticated remote attacker may be able to exploit them. Patched releases were published the same day.

PHP is a programming language used by many websites and business systems. According to W3Techs, 69.3% of websites whose server-side language is known use PHP.

The officially recommended emergency settings only reduce exposure; updating to the official patched release is the only complete fix. That is why we are completing the official update on every system after the emergency mitigation.
