The ThumbPress plugin for WordPress is vulnerable to unauthorized access in versions up to and including 6.2.1. This is due to missing capability checks and nonce verification in the send_deactivation_survey() function registered via the wp_ajax_pl-plugin-deactivation AJAX action. This makes it possible for authenticated attackers, with Subscriber-level access and above, to deactivate the ThumbPress plugin on the affected site by sending a crafted POST request to admin-ajax.
