Delayed Email Notifications for Contact Form 7 Security & Risk Analysis

The plugin "delayed-notifications-for-contact-form-7" v1.1.1 exhibits a mixed security posture. On the positive side, it demonstrates good practices by exclusively using prepared statements for SQL queries and generally implementing proper output escaping. The absence of known vulnerabilities and critical taint flows is also a strong indicator of a secure development history. However, a significant concern arises from its attack surface, specifically the presence of two AJAX handlers that lack authentication checks. This exposes the plugin to potential unauthorized actions if these handlers can be triggered by unauthenticated users, which is a critical oversight in its current configuration.
