Django 4.2.15 fixes three security issues with severity “moderate”, one security issue with severity “high”, and a regression in 4.2.14.
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.
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.
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.
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.
Fixed a regression in Django 4.2.14 that caused a crash in
LocaleMiddleware when processing a language code over 500 characters
(#35627).
