Vulnerability

Incorrect Conversion between Numeric Types

Description

django-filter is a generic system for filtering Django QuerySets based on user selections. In django-filter, 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. + 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.
