EMI Calculator Security & Risk Analysis

The 'rio-emi-calculator' plugin version 1.4.0 exhibits a mixed security posture. On the positive side, the static analysis reveals no dangerous functions, no direct SQL queries (all are prepared), no file operations, no external HTTP requests, and no vulnerabilities recorded in its history. This indicates a generally cautious approach to some security-sensitive areas.

However, significant concerns arise from the lack of output escaping. With 14 total outputs and 0% properly escaped, this plugin is highly susceptible to Cross-Site Scripting (XSS) vulnerabilities. Any user-supplied data that is displayed on the frontend without proper sanitization can be exploited by attackers. Additionally, the absence of nonce checks and capability checks on the single shortcode, while not explicitly flagged as unprotected by the 'Total entry points' metric, suggests a potential for privilege escalation or unauthorized execution if the shortcode's functionality is sensitive.

The plugin's vulnerability history being completely clear is a good sign, but it does not negate the immediate risks identified in the code analysis. The lack of output escaping is the most critical and actionable finding, demanding immediate attention to mitigate XSS risks. The absence of authentication checks on the shortcode is a secondary, but still important, area for improvement.
