LMP Pregnancy Calculator Security & Risk Analysis

The 'lmp-pregnancy-calculator' plugin, version 1.0.3, exhibits a generally good security posture based on the provided static analysis. The absence of dangerous functions, external HTTP requests, file operations, and the use of prepared statements for all SQL queries are positive indicators. Furthermore, the high percentage of properly escaped output suggests an awareness of common cross-site scripting vulnerabilities.

However, several critical security concerns are present. The complete lack of nonce checks and capability checks across all entry points, including the single shortcode, is a significant oversight. This leaves the plugin vulnerable to CSRF attacks and privilege escalation if the shortcode's functionality is sensitive. While there is no known vulnerability history, this should not be taken as a guarantee of future safety, especially given the identified weaknesses in authentication and authorization.

In conclusion, while the plugin has adopted some good security practices like prepared statements and output escaping, the fundamental absence of nonce and capability checks on its entry points represents a notable weakness that could be exploited. Addressing these authentication and authorization gaps should be a priority to improve the plugin's overall security.
