## Description

Django before 1.11.27, 2.x before 2.2.9, and 3.x before 3.0.1 allows
account takeover. A suitably crafted email address (that is equal to an
existing user's email address after case transformation of Unicode
characters) would allow an attacker to be sent a password reset token for
the matched user account. (One mitigation in the new releases is to send
password reset tokens only to the registered user email address.)
