CC Canadian Mortgage Calculator Security & Risk Analysis

The "cc-canadian-mortgage-calculator" plugin v2.1.1 exhibits a mixed security posture. While the static analysis shows no dangerous functions, raw SQL queries, or external HTTP requests, and the fact that there are no unpatched CVEs is positive, significant concerns remain. A notable weakness is the low rate of proper output escaping (32%), which indicates a high potential for Cross-Site Scripting (XSS) vulnerabilities, a pattern corroborated by its vulnerability history which lists a past medium severity XSS. The plugin also lacks nonce and capability checks, and its single shortcode represents an entry point without any authorization checks, further increasing the risk of unauthorized access or execution of actions. The absence of taint analysis flows, while seemingly positive, could also suggest a lack of comprehensive security testing or a very limited code complexity, rather than a truly secure implementation. Overall, the plugin has some good practices regarding database interaction and external communication, but the significant lack of output sanitization and authorization checks on its entry points presents a substantial risk.
