Smart Calculator Builder With Google Sheets – Build Interactive Calculators with Google Sheets at Backend Security & Risk Analysis

The 'smart-cost-builder-with-google-sheets' plugin version 1.2 presents a mixed security posture. On the positive side, the plugin demonstrates good practices by exclusively using prepared statements for its SQL queries and avoiding external HTTP requests, which significantly reduces common web attack vectors. The static analysis indicates no directly exploitable critical or high severity vulnerabilities like dangerous functions or unsanitized taint flows. Furthermore, the plugin has no recorded vulnerability history, suggesting a history of secure development.

However, several areas raise concerns. The plugin exhibits a lack of input validation and output escaping, with only 40% of outputs being properly escaped. This is a significant risk, as unescaped output can lead to Cross-Site Scripting (XSS) vulnerabilities. Additionally, the absence of nonce checks and capability checks for its entry points (shortcodes) means that any user, regardless of their role or permissions, could potentially trigger shortcode functionality, opening the door to unauthorized actions or information disclosure. The bundled jQuery library is also outdated, presenting a potential vulnerability if the library itself has known exploits.

In conclusion, while the plugin avoids some severe vulnerability classes and has a clean history, the lack of proper output escaping and security checks on its entry points creates notable risks, particularly for XSS and unauthorized execution. The outdated bundled library is a minor but present concern. Addressing these issues would significantly improve the plugin's security.
