The InstaWP Connect plugin for WordPress is vulnerable to unauthorized access of data, modification of data and loss of data due to a missing capability check on the 'events_receiver' function in versions up to, and including, 0.0.9.18. This makes it possible for unauthenticated attackers to add, modify or delete post and taxonomy, install, activate or deactivate plugin, change customizer settings, add or modify or delete user including administrator user.
