Django 4.2.16 release notes

September 3, 2024

Django 4.2.16 fixes one security issue with severity "moderate" and one security issue with severity "low" in 4.2.15.

CVE-2024-45230: Potential denial-of-service vulnerability in django.utils.html.urlize()

urlize and urlizetrunc were subject to a potential denial-of-service attack via very large inputs with a specific sequence of characters.

CVE-2024-45231: Potential user email enumeration via response status on password reset

Due to unhandled email sending failures, the 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.
