Contact Info Security & Risk Analysis

The "contact-info" plugin v3.1.8 demonstrates a generally good security posture based on the provided static analysis. The absence of any known CVEs in its history and the analysis showing no critical or high severity taint flows are positive indicators. Furthermore, the plugin utilizes prepared statements for all its SQL queries, which is a strong defense against SQL injection vulnerabilities. The presence of a nonce check and a limited attack surface with no unprotected entry points are also commendable security practices.

However, there are areas for improvement. A significant concern is the low percentage of properly escaped output (29%). This suggests a high risk of Cross-Site Scripting (XSS) vulnerabilities, where malicious scripts could be injected and executed in users' browsers if untrusted data is directly rendered without sufficient sanitization. The lack of capability checks on the single shortcode entry point, while not explicitly a direct vulnerability if the shortcode is deemed benign, could be a weakness if its functionality were to evolve to handle sensitive operations.

In conclusion, while the "contact-info" plugin has avoided historical vulnerabilities and implements some crucial security measures like prepared statements, the substantial output escaping issue represents a notable risk that should be addressed promptly. Strengthening output sanitization would significantly improve the plugin's overall security.
