HIGH

Django 2.2-2.2.25, 3.2-3.2.10, 4.0-4.0.0 - Information Disclosure via dictsort Template Filter

Title source: llm

Description

An issue was discovered in Django 2.2 before 2.2.26, 3.2 before 3.2.11, and 4.0 before 4.0.1. Due to leveraging the Django Template Language's variable resolution logic, the dictsort template filter was potentially vulnerable to information disclosure, or an unintended method call, if passed a suitably crafted key.
