The Contact Form by Supsystic WordPress plugin before 1.11.1 does not validate a CSRF token or request origin on two administrator-only actions that bulk-delete captured form submissions and wipe a form's statistics, allowing attackers to permanently destroy a site's stored contact leads and analytics by tricking a logged-in administrator into sending a forged request.
