PHP & Node.js version check
PHP and Node.js keep releasing fixes for serious flaws. Enter your domain and we look at the PHP or Node.js version your website shows every visitor, then compare it with the latest security release.
The security release we compare with
The PHP and Node.js security releases of 21 October 2026. Each time a new security release comes out, we update what we compare with.
PHP
Two critical flaws (CVE-2026-109618, CVE-2026-109619, CVSS v4 9.2) can let an attacker run code on the server from afar. Fixed in 8.2.35, 8.3.36, 8.4.27 or 8.5.12; every older version of those series is affected.
PHP 8.2 gets no security fixes after 31 December 2026. Plan a move to a newer series.
Node.js
One high-severity flaw (CVE-2026-111497) in the Brotli decoder can permit remote code execution. Fixed in 22.23.4, 24.22.1 or 26.12.1. End-of-Life versions are always affected.
What we look at
- The X-Powered-By and Server headers, which often show a version (PHP/8.4.26).
- Cookie names that PHP and Node.js frameworks set, such as PHPSESSID or connect.sid (names only, never values).
- Addresses ending in .php in your home page’s redirects.
- The generator tag of CMSs that run on PHP, such as WordPress, Joomla or Drupal.
