CVE-2026-4277 [CRITICAL] CWE-639 Django: Django: Privilege Abuse via Forged POST Data in GenericInlineModelAdmin
Django: Django: Privilege Abuse via Forged POST Data in GenericInlineModelAdmin

As a result, unauthorized inline model instances could be added, potentially leading to privilege abuse or unauthorized data manipulation within the application.
Mitigation: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
