Is Fast 404 Safe to Use in 2026?
Generally Safe
Score 85/100Fast 404 has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The fast404 plugin v1.2 exhibits an exceptionally strong security posture based on the provided static analysis. The absence of any identified dangerous functions, SQL queries not using prepared statements, unescaped output, file operations, external HTTP requests, nonce checks, or capability checks is a testament to robust coding practices. Furthermore, the zero-count for taint analysis flows with unsanitized paths, especially those of critical or high severity, indicates a diligent approach to preventing common injection vulnerabilities. The plugin's vulnerability history further reinforces this positive assessment, showing a complete lack of any recorded CVEs, which suggests a consistent and proactive security focus over time.
While the current analysis reveals no immediate threats or vulnerabilities, the extremely limited attack surface and the lack of explicit security checks (like nonces and capability checks) on the identified entry points (which are currently zero) are noteworthy. In a scenario where new entry points were introduced or existing ones modified without corresponding security controls, this could become a concern. However, based solely on the data presented, fast404 v1.2 appears to be a very secure plugin, demonstrating excellent adherence to secure coding principles and a clean security track record.
