All 404 Redirect to Homepage (v5.5) is a WordPress plugin designed to automatically redirect 404 error pages to a specified destination using 301 SEO redirects. Instead of allowing visitors to encounter broken links, the plugin routes them to the homepage or a custom URL defined by the administrator.

Built for websites running on WordPress, the plugin focuses on improving SEO performance and user experience by minimizing exposure to 404 errors and preserving link equity.

However, because redirection logic directly affects HTTP responses and routing behavior, secure implementation is critical. Improper redirect handling can introduce open redirect vulnerabilities, redirect loops, or SEO manipulation vectors. Therefore, this plugin underwent a structured security audit.
