    Cross-site Scripting (XSS)

    nunjucks is a powerful templating engine.

    Like many templating engines, it automatically HTML encodes any string value included in the template using the {{ some-variable }} notation. These variables are often user-generated, but the HTML Encoding protects the application from Cross-site Scripting (XSS) attacks.

    However, if the variable passed in is an array, no HTML encoding is applied, exposing an easy path to XSS. The risk of exploit is especially high given the fact express, koa and many other Node.js servers allow users to force a query parameter to be an array using the param[]=value notation.

    How to fix Cross-site Scripting (XSS)?

    Upgrade to nunjucks version 2.4.3 or newer.
