Display Custom Fields Security & Risk Analysis

The "display-custom-fields" plugin v1.1.1 exhibits a strong security posture based on the provided static analysis. The code analysis reveals no dangerous functions, all SQL queries utilize prepared statements, and all outputs are properly escaped. There are no file operations or external HTTP requests, indicating a limited potential for code injection or data exfiltration through these vectors. The absence of any taint analysis findings further suggests a lack of exploitable vulnerabilities within the analyzed code flows.

While the static analysis is positive, the absence of any capability checks or nonce checks on the single shortcode entry point is a notable concern. Shortcodes can be invoked by any logged-in user, and without proper checks, they could potentially be used in conjunction with other vulnerabilities or misconfigurations to perform unauthorized actions. The vulnerability history is also clean, with no recorded CVEs, which is a positive indicator of the plugin's development and maintenance practices.

Overall, the plugin demonstrates good coding practices regarding data handling and protection against common code execution vulnerabilities. However, the lack of authorization checks on its sole entry point presents a potential weakness that could be exploited in specific scenarios. The clean vulnerability history is a strength, but it is crucial to maintain vigilance, especially given the identified lack of authorization on the shortcode.
