Description

Django REST framework is a powerful and flexible toolkit for building Web APIs. Prior to 3.17.2, Django REST Framework's rest_framework/renderers.py AdminRenderer.render() uses override_method() to simulate GET and directly invokes view.get() without view.check_permissions() while rendering an invalid write request, allowing a 400 Bad Request HTML response to disclose data from a GET representation that the requester is not permitted to access. This issue is fixed in version 3.17.2.
