DX Remove Unused Custom Fields Security & Risk Analysis

The plugin "dx-remove-unused-custom-fields" v0.1 exhibits a strong security posture regarding its attack surface, with no apparent AJAX handlers, REST API routes, shortcodes, or cron events. The code also demonstrates good practices by utilizing prepared statements for all SQL queries and implementing at least one nonce check. However, a significant concern arises from the fact that 100% of its output is not properly escaped, indicating a potential for Cross-Site Scripting (XSS) vulnerabilities. While there is no known vulnerability history for this plugin, the lack of proper output escaping is a notable weakness that could be exploited.
