The Search & Go - Directory WordPress Theme theme for WordPress is vulnerable to Authentication Bypass via account takeover in all versions up to, and including, 2.7. This is due to insufficient user validation in the search_and_go_elated_check_facebook_user() function This makes it possible for unauthenticated attackers to gain access to other users accounts, including administrators, when Facebook login is enabled.
The product requires authentication, but the product has an alternate path or channel that does not require authentication.
