Directory traversal vulnerability in WP Fastest Cache versions prior to 0.9.1.7 allows a remote attacker with administrator privileges to delete arbitrary files on the server via unspecified vectors.
The wp-fastest-cache plugin before 0.8.4.9 for WordPress has SQL injection in wp-admin/admin-ajax.php?action=wpfc_wppolls_ajax_request via the poll_id parameter.
The WP Fastest Cache plugin through 0.8.9.0 for WordPress allows remote attackers to delete arbitrary files because wp_postratings_clear_fastest_cache and rm_folder_recursively in wpFastestCache.php mishandle ../ in an HTTP Referer header.
