QID 982812: Python (pip) Security Update for webargs (GHSA-fjq3-5pxw-4wj4)

flaskparser.py in Webargs 5.x through 5.5.2 doesn't check that the Content-Type header is application/json when receiving JSON input. If the request body is valid JSON, it will accept it even if the content type is application/x-www-form-urlencoded. This allows for JSON POST requests to be made across domains, leading to CSRF.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.
