Source description from Wordfence Intelligence, credited to Maktoum (bRpsd).
The Welcart e-Commerce plugin for WordPress is vulnerable to Session Fixation in all versions up to 2.12.1 (exclusive). This is due to the session value coming from user supplied input. This makes it possible for unauthenticated attackers to take over other user's session if they can obtain the session token.
