# Django 4.2.15 release notes

August 6, 2024

Django 4.2.15 fixes three security issues with severity «moderate», one security issue with severity «high», and a regression in 4.2.14.

## CVE-2024-41989: Memory exhaustion in `django.utils.numberformat.floatformat()`

If `floatformat` received a string representation of a number in scientific notation with a large exponent, it could lead to significant memory consumption.

To avoid this, decimals with more than 200 digits are now returned as is.

## CVE-2024-41990: 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-2024-41991: Potential denial-of-service vulnerability in `django.utils.html.urlize()` and `AdminURLFieldWidget`

`urlize`, `urlizetrunc`, and `AdminURLFieldWidget` were subject to a potential denial-of-service attack via certain inputs with a very large number of Unicode characters.

## CVE-2024-42005: Potential SQL injection in `QuerySet.values()` and `values_list()`

`QuerySet.values()` and `values_list()` methods on models with a `JSONField` were subject to SQL injection in column aliases, via a crafted JSON object key as a passed `*arg`.

## Bugfixes

- Fixed a regression in Django 4.2.14 that caused a crash in `LocaleMiddleware` when processing a language code over 500 characters (#35627).
