Django 2.1.2 release notes
==========================

*October 1, 2018*

Django 2.1.2 fixes a security issue and several bugs in 2.1.1. Also, the latest
string translations from Transifex are incorporated.

CVE-2018-16984: Password hash disclosure to "view only" admin users
===================================================================

If an admin user has the change permission to the user model, only part of the
password hash is displayed in the change form. Admin users with the view (but
not change) permission to the user model were displayed the entire hash. While
it's typically infeasible to reverse a strong password hash, if your site uses
weaker password hashing algorithms such as MD5 or SHA1, it could be a problem.
