Advisory

Source description from Wordfence Intelligence, credited to Rafshanzani Suhada.

The WP Client Reports plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 1.0.16 via the wp_client_reports_send_email_report_from_ajax() function due to a missing capability check. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to extract sensitive data, including information stored in client reports. Please note that this still appears to be vulnerable to Cross-Site Request Forgery.
