Date Time Field Add-On for Gravity Form Security & Risk Analysis

The static analysis of gf-datetime-field-add-on v1.3.6 reveals a plugin with an extremely limited attack surface, showing zero AJAX handlers, REST API routes, shortcodes, or cron events. This absence of common entry points is a strong indicator of good security design. Furthermore, the code analysis shows no dangerous functions, no file operations, no external HTTP requests, and importantly, all SQL queries are properly prepared. This demonstrates a commitment to preventing common web vulnerabilities like SQL injection.

However, a notable concern arises from the output escaping. With 15 total outputs and only 60% properly escaped, there is a significant risk of Cross-Site Scripting (XSS) vulnerabilities. This means user-supplied or dynamic data might be rendered on a page without adequate sanitization, allowing attackers to inject malicious scripts. The complete absence of nonce checks and capability checks on potential (though currently non-existent) entry points, while less critical with zero entry points, could become a risk if new functionality is added without proper security considerations.

The plugin's vulnerability history is clean, with zero recorded CVEs. This, combined with the strong static analysis findings regarding SQL and dangerous functions, suggests a historically well-maintained and secure plugin. The primary weakness identified is the insufficient output escaping, which represents a tangible risk. In conclusion, while the plugin exhibits excellent practices in preventing injection attacks and maintaining a minimal attack surface, the XSS risk due to poor output escaping warrants attention.
