Mozilla: >> Nunjucks >> 0.1.7 Security Vulnerabilities
In Nunjucks versions prior to version 3.2.4, it was
possible to bypass the restrictions which are provided by the autoescape
functionality. If there are two user-controlled parameters on the same
line used in the views, it was possible to inject cross site scripting
payloads using the backslash \ character.

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.
