Session IDs have been removed from the database. This code change may result in breaking changes if merchants have customizations or installed extensions that use the raw session IDs stored in the database.
Restricted admin access to Media Gallery folders. Default Media Gallery permissions now allow only directory operations (view, upload, delete, and create) that are explicitly allowed by configuration. Admin users can no longer access media assets through the Media Gallery that were uploaded outside of the
wysiwyg directories. Administrators who want to access media assets must move them to an explicitly allowed folder or adjust their configuration settings. See Modify Media Library folder permissions.
Lowered limits to GraphQL query complexity. The GraphQL maximum allowed query complexity has been lowered to prevent Denial-of-Service (DOS) attacks. See GraphQL security configuration.
Recent penetration test vulnerabilities have been fixed in this release.
