Diving Calculators Security & Risk Analysis

The "diving-calculators" plugin v1.1.0 exhibits a mixed security posture. On the positive side, it demonstrates excellent practices in handling SQL queries, exclusively using prepared statements, and shows a high degree of diligence in output escaping. The absence of known vulnerabilities in its history is also a strong indicator of good development and maintenance. However, a significant concern arises from the presence of two AJAX handlers that completely lack authentication checks. This creates a direct and unprotected attack surface, which is a critical oversight. The lack of taint analysis data and the absence of nonce and capability checks on these AJAX handlers further exacerbate the risk, as there are no readily apparent security mechanisms in place to validate incoming requests.
