### Impact 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.

#### Example If the user-controlled parameters were used in the views similar to the following: ``` <script> let testObject = { lang: '{{ lang }}', place: '{{ place }}' }; </script> ```

It is possible to inject XSS payload using the below parameters: ``` https://<application-url>/?lang=jp\&place=};alert(document.domain)// ```

### Patches The issue was patched in version 3.2.4.
