Outdated CMS Version

Updated August 2026·SecScanner Team

WordPress, Joomla and Drupal publish their version number in meta generator tags, feeds and asset URLs. An outdated version tells an attacker exactly which public exploits will work.

Why It Matters

CMS vulnerabilities are mass-exploited: once a fix ships, the patch itself becomes the exploit recipe, and unpatched sites are found by automated scanning rather than targeted effort. End-of-life branches (WordPress 5.x, Drupal 9, Joomla 3) receive no security updates at all.

How We Check

We read the `<meta name="generator">` tag, RSS generator elements and versioned asset query strings to identify the CMS and its version, then compare it against the currently supported release branches.

How to Fix

Upgrade to the current major branch (WordPress 6.7+, Joomla 5.x, Drupal 10+) and enable automatic minor/security updates. Keep plugins and themes patched too — most CMS compromises arrive through an extension, not the core. Remove the generator tag so the version is not advertised.
