Koko Analytics – Privacy-Friendly WordPress Analytics Security & Risk Analysis

Koko Analytics v2.2.4 exhibits a mixed security posture. While the plugin demonstrates good practices by implementing numerous capability checks (20) and including nonce checks (7), the significant number of SQL queries (129 total) with a notable portion not using prepared statements (36%) raises a concern for potential SQL injection vulnerabilities. The output escaping also falls short, with only 54% of outputs being properly escaped, indicating a risk of Cross-Site Scripting (XSS) vulnerabilities. The vulnerability history, although no longer unpatched, shows a past of high and medium severity issues, including SQL Injection and XSS. This pattern suggests that while past vulnerabilities have been addressed, the underlying code practices might still be susceptible to similar issues if not continuously monitored and refactored.

The static analysis reveals no critical or high severity taint flows, which is positive. However, the 46% of SQL queries not using prepared statements is a significant area for improvement. Coupled with the low percentage of properly escaped outputs, these factors suggest a considerable risk of vulnerabilities that could be exploited. The vulnerability history, with past high severity SQL injection and XSS, reinforces these concerns. Despite the presence of security checks, the identified code signals indicate that the plugin's developers should prioritize more robust input validation and output sanitization to mitigate the risks of common web vulnerabilities.
