Gutenberg Custom Fields Security & Risk Analysis

Based on the provided static analysis and vulnerability history, the "gutenberg-custom-fields" plugin v1.5.6 exhibits a strong security posture. The code analysis reveals no identified dangerous functions, all SQL queries utilize prepared statements, and output appears to be properly escaped. Furthermore, there are no observed file operations or external HTTP requests, and the plugin does not appear to introduce any significant attack surface through AJAX handlers, REST API routes, shortcodes, or cron events, with a complete lack of unprotected entry points.

The absence of any recorded vulnerabilities in its history, including critical or high-severity issues, further reinforces this positive assessment. This suggests a commitment to secure coding practices by the developers and a consistent track record of stability. The lack of identified taint flows with unsanitized paths also indicates that user-supplied data is likely handled safely.

In conclusion, this plugin appears to be well-developed from a security perspective. The thorough implementation of prepared statements, output escaping, and the absence of exploitable entry points are significant strengths. The clean vulnerability history is also a major positive. While the complete absence of nonce and capability checks on entry points (due to zero entry points) is technically not a weakness in this specific instance, it's a general area to monitor for any future expansions of functionality that might introduce such points.
