Weak Password Recovery Mechanism for Forgotten Password
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.)
CWE-640 - Weak Password Recovery Mechanism for Forgotten Password
The software contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak.
