Calculadora de Frete e Campos Checkout para o Brasil Security & Risk Analysis

The "woo-better-shipping-calculator-for-brazil" plugin version 4.10.0 presents a mixed security posture. On the positive side, the code demonstrates good practices regarding output escaping, SQL query preparation, and a complete absence of file operations and dangerous functions. This indicates a conscientious development approach to preventing common web vulnerabilities. However, a significant concern lies in the substantial attack surface exposed without proper authentication or authorization checks. All 10 AJAX handlers and 1 REST API route lack these crucial security measures, making them prime targets for exploitation if user-supplied data can be manipulated. The vulnerability history is clean, with no known CVEs, which is a strong positive indicator of the plugin's overall security maturity. Despite the lack of past vulnerabilities, the current static analysis reveals a critical oversight in access control for a significant portion of its entry points.
