Django-filter 2.4.0 includes a fix for CVE-2020-15225: In django-filter before version 2.4.0, automatically generated 'NumberFilter' instances, whose value was later converted to an integer, were subject to potential DoS from maliciously input using exponential format with sufficiently large exponents. Version 2.4.0+ applies a 'MaxValueValidator' with a a default 'limit_value' of 1e50 to the form field used by 'NumberFilter' instances. In addition, 'NumberFilter' implements the new 'get_max_validator()' which should return a configured validator instance to customise the limit, or else 'None' to disable the additional validation. Users may manually apply an equivalent validator if they are not able to upgrade.

django-filter is a generic system for filtering Django QuerySets based on user selections. In django-filter before version 2.4.0, automatically generated `NumberFilter` instances, whose value was later converted to an integer, were subject to potential DoS from maliciously input using exponential format with sufficiently large exponents. Version 2.4.0+ applies a `MaxValueValidator` with a a default `limit_value` of 1e50 to the form field used by `NumberFilter` instances. In addition, `NumberFilter` implements the new `get_max_validator()` which should return a configured validator instance to customise the limit, or else `None` to disable the additional validation. Users may manually apply an equivalent validator if they are not able to upgrade. See CVE-2020-15225.
