PHP Patched Against PHP2Shell: Save php -v Output as Potential Court Evidence
Two critical remote code execution vulnerabilities tracked as CVE-2026-109618 and CVE-2026-109619 were disclosed on October 21, 2026, affecting the PHP core interpreter across all versions below 8.2.35, 8.3.36, 8.4.27, and 8.5.12. The flaws, collectively called PHP2Shell, carry a CVSS 4.0 score of 9.2 and allow unauthenticated attackers to execute arbitrary code on servers running WordPress, 1C-Bitrix, Drupal, OpenCart, Laravel, and other frameworks. Official patches have been released, yet organizations must also restart PHP-FPM, web servers, and queue workers to fully eliminate the vulnerable code from memory. Russian regulators may impose fines up to 15 million rubles for personal data leaks stemming from unpatched instances, and courts will examine documentation proving when and how the vulnerabilities were addressed. Security teams are advised to preserve command outputs from php -v and php-fpm -v along with timestamps and responsible-party records. If signs of compromise are detected, logs must be retained before any remediation steps are taken, and notifications to Roskomnadzor must be filed within 24 hours of confirmed data exposure.
