Wise KPIs Security & Risk Analysis

The "wise-kpis" plugin v2.5.1 demonstrates a strong security posture based on the provided static analysis. The plugin has a very small attack surface with only one AJAX handler, and crucially, this handler includes a nonce check. The code signals are also highly positive, with a very high percentage of SQL queries using prepared statements and output escaping. The absence of dangerous functions, file operations, and critical or high-severity taint flows further reinforces this good standing. The plugin also has no recorded vulnerability history, indicating a clean past and potentially robust development practices.

However, a minor concern arises from the lack of capability checks. While the nonce check is present, the absence of a capability check means that even authenticated users might be able to trigger the AJAX action, regardless of their WordPress role. This is a subtle but important distinction in WordPress security, as it assumes all authenticated users should have access to this functionality. Despite this, the overall picture is one of a well-secured plugin with a focus on preventing common vulnerabilities. The low number of potential entry points and the high rate of secure coding practices make it a relatively safe option, with the main area for potential improvement being the addition of role-based access control.
