Frontend User Notes Security & Risk Analysis

The "frontend-user-notes" plugin version 2.1.1 exhibits a generally strong security posture based on static analysis, with no identified dangerous functions, SQL injection vulnerabilities, file operations, or external HTTP requests. The plugin demonstrates good practices by utilizing prepared statements for all SQL queries and implementing nonce and capability checks on its entry points. A high percentage of output escaping (86%) is also a positive sign. However, the presence of 3 AJAX handlers, while all reportedly checked for authentication, still represents an attack surface that requires careful ongoing scrutiny. The plugin's history includes one known CVE, which was an Authorization Bypass Through User-Controlled Key vulnerability. While this CVE is currently unpatched, its severity was only medium. The fact that the last vulnerability occurred in the future (2026-02-17) is an anomaly and should be investigated as a data integrity issue rather than a current security threat.
