21.10.2026 14:09	Security Advisory - php2shell - critical PHP vulnerabilities (CVE-2026-109618, CVE-2026-109619)	Detailsadd
Security Advisory - php2shell - critical PHP vulnerabilities (CVE-2026-109618, CVE-2026-109619) PHP has released security updates for both vulnerabilities. Update immediately. Official technical details and mitigation guidance are now available. The information below supersedes earlier preliminary statements in this post. AFFECTED PRODUCTS AND FIXED VERSIONS: All unpatched PHP installations serving web requests should be assessed, including PHP-FPM, Apache mod_php, php-cgi, FrankenPHP and LiteSpeed. PHP branch Affected releases Fixed release 8.5 Before 8.5.12 8.5.12 8.4 Before 8.4.27 8.4.27 8.3 Before 8.3.36 8.3.36 8.2 Before 8.2.35 8.2.35 Older branches also require remediation. Distribution packages may contain backported fixes without changing the upstream version number. Each package must be checked against the provider’s security recommendations. Mitigation System administrators should identify all PHP installations, assess the level of risk they pose, and install any available security updates from the respective vendors as soon as possible. For affected systems and applications for which no security updates are yet available, access must be restricted to the ETH internal network or to authorised users until the vulnerabilities have been rectified. Alternatively, where operationally feasible, the affected systems or services should be temporarily taken offline.
