Summary
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. 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. Red Hat severity: Moderate — CVSS 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).
Weakness: CWE-770. Affected Red Hat products: Red Hat Ansible Automation Platform 2; Red Hat Discovery 2; Red Hat Satellite 6; Red Hat Update Infrastructure 4 for Cloud Providers; Red Hat Update Infrastructure 5.
Will not fix / out of support: Red Hat Ansible Automation Platform 2; Red Hat Update Infrastructure 4 for Cloud Providers. Red Hat does not currently list a fixing RHSA for this CVE.
