Background
Django is a popular Python web framework that provides a set of tools and libraries for building web applications. It includes features for user authentication and password management. However, versions of Django before 1.11.27, 2.x before 2.2.9, and 3.x before 3.0.1 are vulnerable to a potential account hijack via the password reset form.
Vulnerability Detail
