Advisories for Npm/Nunjucks package

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in nunjucks.

Nunjucks is a full featured templating engine for JavaScript. Versions 2.4.2 and lower have a cross site scripting (XSS) vulnerability in autoescape mode. In autoescape mode, all template vars should automatically be escaped. By using an array for the keys, such as name[]=<script>alert(1)</script>, it is possible to bypass autoescaping and inject content into the DOM.
