Advisory

Source description from Wordfence Intelligence, credited to Tonn.

The SetSail Membership plugin for WordPress is vulnerable to in all versions up to, and including, 1.0.3. This is due to the plugin not properly verifying a users identity through the social login. This makes it possible for unauthenticated attackers to log in as any user, including administrators and take over access to their account.
