Custom 404 Redirect Security & Risk Analysis

The plugin "custom-404-redirect" v1.2 exhibits a strong security posture based on the provided static analysis. The absence of any detected dangerous functions, SQL injection vulnerabilities (all queries use prepared statements), and output escaping issues, along with no file operations or external HTTP requests, indicates robust coding practices in these areas. The plugin also shows no recorded history of vulnerabilities, which is a positive sign regarding its historical security. However, a significant concern arises from the complete lack of any capability checks, nonce checks, or permission callbacks across all entry points. While the current attack surface is reported as zero, this absence of authorization controls means that if any new entry points were to be introduced in future versions, they would be inherently unprotected. This lack of a foundational security mechanism is a notable weakness.
