CVE-2024-45231: Potential user email enumeration via response status on password reset
Due to unhandled email sending failures, the django.contrib.auth.forms.PasswordResetForm class allowed remote attackers to enumerate user emails by issuing password reset requests and observing the outcomes.
To mitigate this risk, exceptions occurring during password reset email sending are now handled and logged using the django.contrib.auth logger.
Thanks to Thibaut Spriet for the report.
