Website Carbon Calculator Security & Risk Analysis

The website-carbon-calculator plugin version 1.3.8 exhibits a strong security posture based on the provided static analysis and vulnerability history. The code demonstrates excellent adherence to secure coding practices, with all SQL queries using prepared statements and all output properly escaped. The absence of dangerous functions, file operations, and critical/high severity taint flows further enhances its security. The limited attack surface, consisting of only three AJAX handlers, is also a positive indicator, although the lack of explicit capability checks on these handlers represents a minor concern.

Furthermore, the plugin's vulnerability history is entirely clean, with no recorded CVEs of any severity. This indicates a history of secure development and maintenance. The presence of only one external HTTP request is a minimal risk. The plugin's reliance on the Guzzle library is noted but does not present an immediate concern without further analysis of its specific version and potential vulnerabilities within that bundled library.

In conclusion, the website-carbon-calculator plugin appears to be a very secure option. Its strengths lie in its robust use of prepared statements, proper output escaping, and a clean vulnerability record. The primary area for potential improvement would be to implement capability checks on the AJAX handlers to further harden the plugin against unauthorized access, although the current lack of explicit checks combined with the absence of other vulnerabilities does not present an immediate critical threat.
