Vulnerability CVE-2020-7965


Published: 2020-01-29

Description:
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.

Type:

CWE-352

(Cross-Site Request Forgery (CSRF))
