Lightgallery.js 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!

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.
