The wp_ajax_update_plugin function in wp-admin/includes/ajax-actions.php in WordPress before 4.6 makes a get_plugin_data call before checking the update_plugins capability, which allows remote authenticated users to bypass intended read-access restrictions via the plugin parameter to wp-admin/admin-ajax.php, a related issue to CVE-2016-6896.

Multiple cross-site scripting (XSS) vulnerabilities in the request_filesystem_credentials function in wp-admin/includes/file.php in WordPress before 3.0.2 allow remote servers to inject arbitrary web script or HTML by providing a crafted error message for a (1) FTP or (2) SSH connection attempt.

Cross-site scripting (XSS) vulnerability in wp-live.php in the WP Live.php module 1.2.1 for WordPress allows remote attackers to inject arbitrary web script or HTML via the s parameter. NOTE: some of these details are obtained from third party information.

importbuddy.php in the BackupBuddy plugin 1.3.4, 2.1.4, 2.2.25, 2.2.28, and 2.2.4 for WordPress does not require that authentication be enabled, which allows remote attackers to obtain sensitive information, or overwrite or delete files, via vectors involving a (1) direct request, (2) step=1 request, (3) step=2 or step=3 request, or (4) step=7 request.

Before version 4.8.2, WordPress mishandled % characters and additional placeholder values in $wpdb->prepare, and thus did not properly address the possibility of plugins and themes enabling SQL injection attacks.
