Preview Calculator for WooCommerce Security & Risk Analysis

Based on the provided static analysis and vulnerability history, the 'wc-preview-calculator' plugin version 1.1.1 exhibits a generally strong security posture. The absence of any identified AJAX handlers, REST API routes, shortcodes, or cron events significantly limits the plugin's attack surface, with no entry points found to be unprotected. The code analysis also shows excellent practices regarding dangerous functions, SQL queries (all using prepared statements), file operations, and external HTTP requests. Furthermore, the high percentage of properly escaped output suggests good attention to preventing cross-site scripting (XSS) vulnerabilities.

While the plugin's code appears to be well-secured in terms of potential injection or direct manipulation, the complete lack of nonce and capability checks across all potential (though absent) entry points is a notable concern. This implies that if any new entry points were to be introduced in future versions, they might lack essential authorization and security verification mechanisms by default. The vulnerability history is also entirely clean, with no past CVEs reported, which is a positive indicator of the plugin's past security development. However, this clean history, combined with the absence of checks, means there's no historical data to suggest how the plugin would handle security issues if they arose.

In conclusion, 'wc-preview-calculator' v1.1.1 demonstrates a robust foundation with a minimal attack surface and secure coding practices for the features analyzed. The primary weakness lies in the complete absence of authorization checks (nonces and capabilities), which, while not directly exploitable in this version due to the lack of entry points, represents a potential future risk. The lack of any historical vulnerabilities is a strength, but it also means the plugin has not been tested against security flaws in practice.
