Magento Open Source 2.2.3 Release Notes

Patch code and release notes published on February 27, 2018.

Release notes updated on March 22, 2018.

We are pleased to present Magento Commerce 2.2.3. This release includes 35 enhancements to product security, a change to the Magento Admin to support recent USPS shipping changes, and a copyright update. And thanks to our community members, it also includes enhancements to ACL control for cache management through Magento Admin.

For security reasons, this release limits the ability to use symlinks for /media and other folders. If you are using symlinks for deployment, or if your /media is using symlinks, you may experience problems uploading or removing images. Magento will announce a fix for this issue when available. See GitHub-13929 for more information.

Highlights

Look for the following highlights in this release:

  • Enhancements that help close cross-site request forgery (CSRF), unauthorized data leaks, and authenticated Admin user remote code execution vulnerabilities. See Magento Security Center for more information.
  • Support for Elasticsearch 5.x. See Install and configure Elasticsearch for more information about using Elasticsearch with Magento. Fix submitted by community member Aurélien Foucret.

  • Change to Magento Admin to support recent USPS shipping changes. On February 23, 2018, USPS removed APIs that support the creation of shipping labels without postage. In response, we’ve removed this functionality from the Magento Admin. Consequently, you cannot create and print shipping labels that do not have postage applied. If you require USPS postage printing capabilities, please visit Magento Shipping to learn more, and explore various shipping extensions on Magento Marketplace.

  • New layers of control for cache management tasks managed through the Magento Admin. This release introduces finer permissions for cache management tasks such as flushing cache storage, flushing the Magento cache, and refreshing cache types. Fix submitted by community member Bartosz Herba.

  • Updated copyright to 2018.

Security enhancements

Magento 2.2.3 includes multiple security enhancements. Although this release includes these enhancements, no confirmed attacks related to these issues have occurred to date. However, certain vulnerabilities can potentially be exploited to access customer information or take over administrator sessions, so we recommend that you upgrade your Magento software to the latest version as soon as possible.

See Magento Security Center for more information.
