Loan Calculator WP Security & Risk Analysis

The 'loan-calculator-wp' plugin version 2.1.0 exhibits a generally good security posture with some notable concerns. It demonstrates strong practices in SQL query handling, with 100% of queries using prepared statements, and robust output escaping, ensuring all 790 output points are properly sanitized. The absence of known CVEs and a clean vulnerability history further contribute positively to its security. The plugin also avoids bundling libraries, which can often be a source of outdated and vulnerable components. However, the presence of two AJAX handlers without authentication checks represents a significant security weakness. These entry points could potentially be exploited by unauthenticated users to perform unintended actions within the plugin, depending on their functionality. While taint analysis did not reveal any critical or high-severity issues, the lack of capability checks on any entry points is a missed opportunity to enforce user roles and permissions, which could otherwise mitigate risks associated with the unprotected AJAX handlers.
