The Stream plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.2.0. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to access all Stream activity records via the Heartbeat API.
