3. Enable the Update Manager module (Admin → Extend) to receive in-dashboard update notifications.
4. Review Drupal's Security Advisories page and subscribe to security email alerts for your installed version.

What is cms version?

Every website is built on a content management system (CMS) — software like WordPress, WooCommerce, Shopify, Wix, or Magento that powers your store behind the scenes. Just like your phone's operating system, this software releases regular updates that fix bugs, patch security holes, and add new features. Running an outdated version means your store is using software the vendor no longer actively protects — and that attackers actively target. A "cms_version" finding means your platform or a core component of it has been detected as out-of-date or approaching end-of-life.

Outdated CMS versions are the single most common entry point for store hacks: attackers maintain public databases of known vulnerabilities tied to specific version numbers, and they run automated bots that scan millions of sites daily looking for easy targets. A successful breach can result in stolen customer payment data (triggering PCI-DSS fines and card-network penalties), customer account takeovers, malware injected into your storefront that drives customers away, and Google Safe Browsing warnings that tank your organic traffic overnight. Beyond security, running end-of-life software means you stop receiving performance improvements and compatibility updates — slowing your site and hurting your search rankings. Many payment processors and hosting providers will also suspend service for stores running critically outdated platforms.
