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.
