Node.Security

Security Audit of Tern

ISGroup SRL performed an automated Code Review (not a real Static Analysis, more a grep-on-steroid) of this NodeJS project in order to identify potential security vulnerabilities. We do not guarantee that all the findings are valid, and for sure there are plenty of false-positives and false-negatives (undetected issues) but it's free and your project could benefit from this security analisys. The following data is also available in JSON format!

Missing Security Features
Issue Description
Missing Security Header - X-Frame-Options (XFO) X-Frame-Options (XFO) header provides protection against Clickjacking attacks.
Missing Security Header - Content-Security-Policy (CSP) Content Security Policy (CSP), a mechanism web applications can use to mitigate a broad class of content injection vulnerabilities, such as cross-site scripting (XSS). CSP Header was not found.
