Avoid Duplicate Titles Security & Risk Analysis

The "avoid-duplicate-titles" plugin version 2.2.0 exhibits a generally strong security posture based on the provided static analysis and vulnerability history. The plugin demonstrates good practices by implementing nonce and capability checks on its single AJAX entry point, and all SQL queries are properly prepared, mitigating common injection risks. Furthermore, the lack of file operations, external HTTP requests, and the high percentage of properly escaped output are positive indicators. The absence of any recorded vulnerabilities in its history further strengthens this assessment.
