How to fix cms version on Magento Open Source
Identify your ecommerce platform and CMS version, then ensure it is always kept up to date to protect your store from security vulnerabilities and avoid loss of vendor support.
Steps for Magento Open Source
- Run `php bin/magento --version` via SSH to check your current version.
- Review the Magento Open Source GitHub releases page for the latest version and security patches.
- Back up your database and files, then use Composer to pull in updates: `composer require magento/product-community-edition=<new-version> --no-update && composer update`.
- Run the post-upgrade commands: `php bin/magento setup:upgrade`, `php bin/magento setup:di:compile`, `php bin/magento cache:flush`.
- Test your store on a staging environment before deploying to production.
What is cms version?
Every online store runs on a content management system (CMS) or ecommerce platform — such as Shopify, WooCommerce, Magento, BigCommerce, or Wix. Each platform releases version updates that fix bugs, patch security holes, and add new features. When a security scanner cannot detect which platform or version your store is running, it usually means the information is hidden (which can be good), outdated, or the platform is self-hosted and unpatched. Keeping your CMS on a current, supported version is one of the most fundamental maintenance tasks for any online store.
Running an outdated or unknown CMS version is one of the leading causes of store hacks, data breaches, and payment fraud — all of which can result in lost customer trust, fines under regulations like GDPR and PCI-DSS, and even having your store blacklisted by Google (which directly destroys organic traffic overnight). Search engines also use site health signals — a hacked or flagged site loses rankings fast and is extremely difficult to recover. On the revenue side, a compromised checkout destroys conversions and can get your payment processor account terminated. Staying on a supported, up-to-date version means you receive security patches as soon as vulnerabilities are discovered, before attackers can exploit them.
