## Technical details

The Easy Appointments plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check and missing nonce verification on the 'ea_delete_multiple_connections' AJAX action. This vulnerability affects all versions up to and including 3.12.27. An authenticated attacker with Contributor-level permissions or higher can exploit this flaw to send requests that delete arbitrary records from the 'wp_ea_connections' database table. This occurs because the plugin fails to verify if the user has the appropriate administrative rights or a valid security token (nonce) before executing the deletion logic. The impact is a disruption of the plugin's core booking functionality and potential data loss.
