Details

Cross-Site Scripting in nunjucks Affected versions of `nunjucks` do not properly escape specially structured user input in template vars when in auto-escape mode, resulting in a cross-site scripting vulnerability. ## Proof of Concept By using an array for the keys in a template var, escaping is bypassed. ```javascript name[]=<script>alert(1)</script> ``` A full PoC is available in the references section. ## Recommendation Update to version 2.4.3 or later.
