Webfontloader Code Review

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.
Missing Security Header - Strict-Transport-Security (HSTS)	Strict-Transport-Security (HSTS) header enforces secure (HTTP over SSL/TLS) connections to the server.
Missing 'httpOnly' in Cookie	JavaScript can access Cookies if they are not marked httpOnly.
Infromation Disclosure - X-Powered-By	Remove the X-Powered-By header to prevent information gathering.
Missing Security Header - X-Content-Type-Options	X-Content-Type-Options header prevents Internet Explorer and Google Chrome from MIME-sniffing a response away from the declared content-type.
Missing Security Header - X-Download-Options: noopen	X-Download-Options header set to noopen prevents IE users from directly opening and executing downloads in your site's context.
Missing Security Header - X-XSS-Protection:1	X-XSS-Protection header set to 1 enables the Cross-site scripting (XSS) filter built into most recent web browsers.
Missing Security Header - Public-Key-Pins (HPKP)	Public-Key-Pins (HPKP) ensures that certificate is Pinned.
