Mortgage Calculator Free Security & Risk Analysis

The "mortgage-calculator-free" v1.1.0 plugin exhibits a generally good security posture based on the static analysis, with no identified dangerous functions, SQL injection vulnerabilities, or external HTTP requests. The absence of known CVEs and a clean vulnerability history further contribute to a positive assessment. However, a significant concern lies in the low percentage of properly escaped output (12%), indicating a substantial risk of Cross-Site Scripting (XSS) vulnerabilities. While the attack surface is small and appears to have no direct unprotected entry points, the lack of explicit capability checks and nonce checks on its single shortcode is a weakness. This, coupled with the potential for unescaped output from the shortcode's rendering, suggests that malicious actors could potentially inject and execute arbitrary scripts within the WordPress admin or frontend if the shortcode's output is not handled carefully by the theme or other plugins.
