Magento Open Source 2.0.6 Release Notes

We are pleased to present Magento Open Source (formerly Community Edition) 2.0.6. This release includes security enhancements as well as several functional fixes and enhancements.

2.0.6 contains important security updates. Please update to this version or use the latest available Magento version when starting a new project.

Backward-incompatible changes are documented in Magento 2.0 Backward Incompatible Changes.

Fixed issues

  • Varnish no longer returns a 400 bad request error message when clearing its cache . Previously, this issue occurred with Magento instances running on GoDaddy.

Functional enhancements

  • Starting with Magento 2.0.6, Magento provides a more flexible way for you to set file ownership and permissions. Instead of setting permissions explicitly, you only need to make sure files and directories are writable for installation. We provide different suggestions for doing this, depending on whether you access your Magento server with one user account (typical of shared hosting) or two user accounts (typical of private hosting or having your own server). After installation, to further restrict access to files and directories, you can optionally create a file named magento_umask in your Magento root directory. By default, the umask is 002, which means that directories have 775 permissions and files have 664 permissions. For more details, see Magento file system ownership and permissions.
  • You can now use the Redis adapter to provide session storage in Magento 2.0.6. For more information, see Redis for session storage.

Security enhancements

This release includes enhancements to improve the security of your Magento installation. While there are no confirmed attacks related to these issues to date, certain vulnerabilities can potentially be exploited to access customer information or take over administrator sessions. We recommend that you upgrade your existing Magento installation to the latest version as soon as possible.

The following list provides an overview of the security issues fixed in this release. We describe each issue in greater detail in the Magento Security Center.

  • Magento no longer permits an unauthenticated user to remotely execute code on the server through APIs.
  • Magento no longer allows authenticated customers to change other customers’ account information using either SOAP or REST calls. Magento now confirms that the ID of the customer whose account is being edited matches the authentication token in use.
  • Anonymous users can no longer retrieve the private data of registered customers. To prevent malicious attacks of this type, the quote_id_mask table of the Quote API no longer includes a cart id mask value.
  • Several parameters in the payment module are vulnerable to reflected Cross-Site Scripting (XSS) attacks. Existing protection against such malicious parameters is not enough to stop all types of attacks.
  • Magento no longer allows users with minimum privileges (for example, access to the dashboard only) to force re-installation of Magento, which could allow them to potentially execute malicious code.
  • The Magento installation code is no longer accessible once the installation process has completed.
  • When an integration is created, Magento now bases the OAuth consumer key expiration from when the token exchange begins instead of when the consumer key is created. (GITHUB-3449)
  • Only a registered customer can assign a guest cart to himself. Previously, an anonymous user could modify the state (that is, set an active quote) of a registered customer.
  • Magento no longer discloses information about its internal path during installation.
  • Magento no longer discloses the administrator URL to an unauthenticated user during setup.
  • Application error messages no longer include the path to the file where the error occurred.
