Easy Frequently Bought Together for WooCommerce Security & Risk Analysis

The plugin 'easy-frequently-bought-together-for-woocommerce' v1.0.6 demonstrates a generally strong security posture with several good practices in place. Notably, 100% of its SQL queries utilize prepared statements, indicating a defense against SQL injection vulnerabilities. The high percentage of properly escaped output (94%) also suggests good mitigation against Cross-Site Scripting (XSS) attacks. The absence of known CVEs and no recorded past vulnerabilities is a positive indicator of the developers' commitment to security. However, there are significant areas of concern within its attack surface. A substantial number of AJAX handlers (5 out of 9) and all REST API routes (2 out of 2) lack authentication checks. This presents a considerable risk, as these entry points could be exploited by unauthenticated users to trigger potentially harmful actions or expose sensitive information.
