Doc Text:
A flaw was found in Django REST framework. A remote attacker could exploit a vulnerability in the `request.data` parsing mechanism, which bypasses Django's `DATA_UPLOAD_MAX_MEMORY_SIZE` protection. This allows an attacker to send oversized JSON and URL-encoded request bodies, leading to excessive consumption of memory and CPU resources. This could result in a Denial of Service (DoS) for the affected application.

Description OSIDB Bzimport 2026-08-11 19:03:22 UTC
Django REST framework is a toolkit for building Web APIs. Prior to 3.17.2, Django REST Framework's request.data parsing in rest_framework/request.py Request._parse() passes the underlying HttpRequest stream to JSONParser and FormParser for application/json and application/x-www-form-urlencoded bodies, bypassing Django's DATA_UPLOAD_MAX_MEMORY_SIZE protection and allowing oversized request bodies to consume additional memory and CPU. This issue is fixed in version 3.17.2.
