Responsive Mailform ( Plugin Version ) – easy, responsive, contact, mailform Security & Risk Analysis

The responsive-mailform v9.0 plugin exhibits a generally strong security posture based on the provided static analysis. The absence of any known CVEs, critical taint flows, or dangerous function usage is a significant positive indicator. The plugin also demonstrates good practices in its handling of SQL queries, utilizing prepared statements exclusively, and includes basic security measures like nonce and capability checks. However, a notable concern arises from the low percentage of properly escaped output (20%). This could potentially lead to cross-site scripting (XSS) vulnerabilities if user-supplied data is not handled carefully when displayed, especially with only one shortcode as an entry point where output is more likely to be dynamic. The file operation, while present, doesn't have explicit details regarding its security implications without further context, but in isolation, it's a potential area of concern. Overall, the plugin has strengths in its lack of critical flaws and good SQL practices, but the significant lack of output escaping is a weakness that requires attention.
