# Note di rilascio di Django 2.2.21

*4 Maggio 2021*

Django 2.2.21 risolve un problema di sicurezza in 2.2.20.

## CVE-2021-31542: Potential directory-traversal via uploaded files

`MultiPartParser`, `UploadedFile`, and `FieldFile` allowed
directory-traversal via uploaded files with suitably crafted file names.

In order to mitigate this risk, stricter basename and path sanitation is now
applied.
