CVE-2024-45231Network attack vector

User email enumeration via unhandled mail exceptions

Published Oct 8, 2024 · Updated Mar 17, 2025

Observable discrepancy in Django 4.2 before 4.2.16, 5.0 before 5.0.9, and 5.1 before 5.1.1 allows remote attackers to enumerate user emails. PasswordResetForm.send_mail lets email-backend exceptions escape only for registered addresses, producing error responses while unknown addresses complete normally. Exploitation requires an exposed password-reset view and consistently failing email delivery; the bounded consequence is disclosure of registered email addresses.
