Django 2.2.21 fixes a security issue 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. Specifically, empty file names and paths with dot segments will be
|
||
|
|
rejected.
