The WP-CRM System plugin for WordPress is vulnerable to unauthorized access due to missing capability checks on the wpcrm_get_email_recipients and wpcrm_system_ajax_task_change_status AJAX functions in all versions up to, and including, 3.4.5. This makes it possible for authenticated attackers, with subscriber level access and above, to enumerate CRM contact email addresses (PII disclosure) and modify CRM task statuses.
