Security Assurance

Security testing for Everest Forms 3.4.0 was conducted as part of the CleanTalk Plugin Security Certificationprogram, with a focus on both static code analysis and dynamic runtime behavior. This included simulating real-world attack scenarios and testing all input vectors, user roles, endpoints, and file handling features.

We’re pleased to report that Everest Forms has passed all security testing with no critical or high-severity vulnerabilities detected.

✅ Successfully Tested Against:

• SQL Injection (SQLi)
• Cross-Site Scripting (XSS) – Stored & Reflected
• Cross-Site Request Forgery (CSRF)
• Authentication Bypass & Session Manipulation
• Privilege Escalation
• Buffer Overflow
• Denial-of-Service (DoS) Vectors

🔍 Secure Practices Observed:

• ✅ Strong nonce and capability checks prevent CSRF and unauthorized actions across admin and front-end endpoints.
• ✅ File upload and PDF generation features are hardened with MIME type checking, size restrictions, and strict directory scoping.
• ✅ AJAX endpoints are protected with appropriate permission callbacks and CSRF tokens.
• ✅ Spam protection features (reCAPTCHA, hCAPTCHA, Turnstile, Honeypot) are implemented to guard against bot abuse.
• ✅ No insecure third-party libraries or known vulnerable dependencies were detected in the plugin’s bundle.
• ✅ Debugging and internal logging are either disabled in production or sanitized against leakage of sensitive environment data.
