# Django 4.2.3 release notes

*July 3, 2023*

Django 4.2.3 fixes a security issue with severity «moderate» and several bugs
in 4.2.2.

## CVE-2023-36053: Potential regular expression denial of service vulnerability in `EmailValidator`/`URLValidator`

`EmailValidator` and `URLValidator` were subject to potential regular
expression denial of service attack via a very large number of domain name
labels of emails and URLs.

## Bugfixes

- Fixed a regression in Django 4.2 that caused incorrect alignment of timezone
  warnings for `DateField` and `TimeField` in the admin ([#34645](https://code.djangoproject.com/ticket/34645)).
- Fixed a regression in Django 4.2 that caused incorrect highlighting of rows
  in the admin changelist view when `ModelAdmin.list_editable` contained a
  `BooleanField` ([#34638](https://code.djangoproject.com/ticket/34638)).
