All Users Filter Security & Risk Analysis

The "all-users-filter" plugin version 1.4 exhibits a strong security posture based on the provided static analysis. The absence of dangerous functions, the exclusive use of prepared statements for SQL queries, and 100% properly escaped output are significant strengths. Furthermore, the plugin demonstrates good security practice by implementing nonce and capability checks on its entry points, resulting in zero unprotected attack surfaces. The vulnerability history is also clean, with no recorded CVEs, indicating a generally well-maintained codebase.

While the static analysis reveals no critical or high-severity issues like taint flows or unescaped outputs, and the plugin avoids file operations and external HTTP requests, a minor area for consideration could be the number of entry points relative to the checks. With one AJAX handler, having two nonce checks and two capability checks is positive, but it's worth noting that any future expansion of entry points would require diligent adherence to these security practices. The lack of any recorded past vulnerabilities further reinforces the current positive assessment, suggesting a proactive approach to security by the developers.
