Overseas Express Shipment Security & Risk Analysis

The 'overseas-express-shipment' plugin v1.0.2 exhibits a generally good security posture, with several strong security practices in place. The plugin demonstrates a high level of care regarding SQL queries, utilizing prepared statements exclusively, and boasts a very high percentage of properly escaped output, significantly mitigating risks of cross-site scripting (XSS) vulnerabilities. The absence of any recorded vulnerabilities or CVEs in its history is also a positive indicator of developer diligence. However, a notable concern is the presence of one AJAX handler that lacks authentication checks. This unprotected entry point could be exploited by unauthenticated users, potentially leading to unauthorized actions if the handler performs sensitive operations.
