StatsFC Table Security & Risk Analysis

The statsfc-table v2.2.1 plugin exhibits a generally good security posture based on the provided static analysis. It does not utilize dangerous functions, perform file operations, make external HTTP requests, or contain known vulnerabilities. The use of prepared statements for all SQL queries is a strong security practice. However, there are notable concerns regarding output escaping, with less than half of the detected outputs being properly escaped, indicating a potential for cross-site scripting (XSS) vulnerabilities. Additionally, the absence of nonce checks and capability checks across all entry points, including the single shortcode, is a significant weakness. While no critical or high severity taint flows were identified in the limited analysis, the presence of unsanitized paths in the analyzed flows is a red flag that warrants further investigation.

The plugin's history of zero known CVEs is positive, suggesting a good track record. However, this is in the context of a limited attack surface and the potential for unaddressed vulnerabilities due to the lack of robust security checks like nonce and capability checks. The absence of vulnerabilities in the past does not guarantee future security, especially if the identified weaknesses in output escaping and authorization are exploited.

In conclusion, while the plugin has strengths in its SQL handling and lack of external dependencies or dangerous functions, the significant percentage of unescaped output and the complete lack of nonce/capability checks on its shortcode create a tangible risk. The taint analysis, though limited, also points to potential issues with unsanitized paths. Addressing the output escaping and implementing proper authorization checks on the shortcode are critical steps to improve its security.
