ReCaptcha v2 for Contact Form 7 Security & Risk Analysis

The wpcf7-recaptcha plugin, version 1.4.9, exhibits a generally good security posture based on the provided static analysis. The absence of AJAX handlers, REST API routes, shortcodes, and cron events significantly limits its attack surface. The code also demonstrates good practices with 100% of SQL queries using prepared statements and a high percentage of output being properly escaped. The presence of a nonce check is also a positive indicator. However, the plugin does make one external HTTP request, which, without further analysis of its context, represents a potential point of vulnerability if not handled securely. The vulnerability history is completely clean, with no recorded CVEs, suggesting a well-maintained and secure plugin over time. The lack of any taint analysis findings further reinforces the impression of a secure codebase. Overall, the plugin appears to be robustly developed with strong security awareness, with the minor concern being the unscrutinized external HTTP request.
