MoExRate Security & Risk Analysis

The "moexrate" plugin v1.0.0 exhibits a mixed security posture. On the positive side, it demonstrates good practices by avoiding dangerous functions, all SQL queries are properly prepared, and there are no recorded vulnerabilities or known CVEs. This suggests a development team that is mindful of common pitfalls.

However, a significant concern arises from the complete lack of output escaping. With 12 total outputs, none of which are properly escaped, this opens the plugin to a high risk of Cross-Site Scripting (XSS) vulnerabilities. Any user-supplied data that is displayed by the plugin without sanitization could be exploited by attackers to inject malicious scripts. Additionally, the absence of nonce and capability checks on its entry points, while seemingly having a small attack surface reported, means that if any new entry points were to be introduced in future versions, they might also be unprotected, creating an indirect risk.

Given the lack of historical vulnerabilities, it's difficult to draw strong conclusions about past security practices. However, the current static analysis highlights a critical weakness in output handling. The overall risk is moderate, primarily driven by the severe lack of output escaping, which is a common vector for significant security breaches.
