GDPR Cookie Compliance – Cookie Banner, Cookie Consent, Cookie Notice for CCPA, EU Cookie Law Security & Risk Analysis

The gdpr-cookie-compliance v5.0.11 plugin exhibits a mixed security posture, with several encouraging signs alongside significant areas of concern. The plugin demonstrates strong practices in output escaping, with 91% of outputs properly escaped, and a commendable absence of dangerous functions, file operations, and critical or high-severity taint flows. However, the attack surface is considerably large and largely unprotected, with 10 AJAX handlers and only 9 of them including authentication checks. This leaves 9 entry points vulnerable to unauthorized execution, presenting a substantial risk for privilege escalation or data manipulation if not properly secured by other means.

The plugin's vulnerability history is a major red flag. While there are no currently unpatched CVEs, the plugin has accumulated 9 medium-severity vulnerabilities in the past, with common types including Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF), and Missing Authorization. This pattern suggests a recurring tendency for vulnerabilities to emerge, particularly those related to input validation and authorization. The most recent vulnerability being in 2025, while seemingly in the future, could indicate a placeholder or an error in the provided data, but if accurate, points to recent, albeit medium, security flaws.

In conclusion, while the plugin has some positive technical security attributes like robust output escaping and a lack of critical taint issues, the unprotected AJAX handlers and the history of medium-severity vulnerabilities, especially those related to authorization and input handling, present a considerable risk. The high number of unprotected entry points and past vulnerability types necessitate careful scrutiny and potentially a more thorough security audit to ensure robust protection against common web attack vectors.
