The IP2Location Country Blocker WordPress plugin before 2.26.5 does not have authorisation and CSRF checks in the ip2location_country_blocker_save_rules AJAX action, allowing any authenticated users, such as subscriber to call it and block arbitrary country, or block all of them at once, preventing users from accessing the frontend.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
