Summary
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. The AdminRenderer component, when processing an invalid write request, can improperly invoke a GET request without adequate permission checks.
This oversight allows an unauthenticated attacker to access data that they are not authorized to view, leading to information disclosure. This vulnerability affects the confidentiality of sensitive information.
Red Hat severity: Moderate — CVSS 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N). Weakness: CWE-425.
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.
